Almost every day we receive phone calls from solicitors or directly from a witness expressing an interest in connecting Skype (public version not Skype for business) to a court or tribunal centre in the UK. Technically yes it is possible for us to connect Skype to a UK Court however it’s not straight forward. 
Skype is only able to connect to other Skype accounts so there is no route to connect (dial) any other video chat service or video conference solution.
We’ve established that UK courts do not use Skype nor do they advocate the use of it, however we do have the technology in place to quite literally ‘bridge’ Skype to any video conference system.

Our video conference bridging service also connects the signals from IP based Skype and other video chat platforms to ISDN and standards based H.323 video conference systems (Polycom, Cisco, Lifesize) which ultimately allows any two video devices to communicate.

As mentioned earlier it is not a straight forward process to link Skype to standards based video conferencing systems, that’s why our experienced engineers do the complicated configurations behind the scenes making it a seamless experience for both the witness and the Court room.

Despite having the ability to connect Skype to court video links we don’t really advertise the fact because we have found Skype to be unreliable and we cannot be totally sure of its security. The only person that dislikes an unreliable video link more than us is the sitting judge, and we’ll let you imagine their reasons for disliking unreliable video links.

So how do we cater for witnesses that want to connect to UK Courts using Skype? We offer them our reliable and secure alternative, Viewme!

Like Skype, Viewme is a application installed on a mac or computer. Viewme gives the user the ability to securely connect to our encrypted bridging service where we are able to connect directly to the courts video link service over ISDN which makes the link reliable and secure.

Another great security feature is that we use unique conference ID’s that are randomly generated for single use only. If the conference ID is not known then access is not permitted, moreover we only generate the conference ID’s the day before the hearing. We know Viewme works well because we have used it extensively since 2013. Both lay and expert witnesses have used the Viewme service to connect to UK Courts over ISDN and indeed across the Martin Dawes (Vodafone bridge) network.

So if you have Skype and want to connect to a Court give us a call because we can help!

Free Business to Business Video Conferencing via iPad

We in the industry knew it wouldn’t be long before someone created an app that connected the iPad directly to any standards-based videoconference codec. Sure enough, Polycom has recently launched their RealPresence™ Mobile app for the iPad. If it is free video conferencing you are looking for, then grab your iPad and search for the Polycom RealPresence™ Mobile app. You won’t be disappointed.We road-tested the RealPresence™ Mobile client in a number of situations and  were pleasantly surprised at the ease of connection, video and audio quality.
We simply launched the app then dialled out to a Tandberg test IP address. No configuration of the router was necessary and we were able to send and receive both video and audio at 384kbps at the first attempt.
We carried out our next test sitting in our local McDonalds restaurant (at lunch time.) With our iPad connected to their network, we dialled into our RMX2000 video bridge. Again, we were connected first time. We entered the meeting pin and then waited for a colleague to connect from an ISDN site. Sure enough, within two clicks we were having an IP to ISDN videoconference over a McDonalds restaurant wifi network while eating burgers and slurping cola.
As part of their new ‘software’-focused offering, aptly named “RealPresence™,” Polycom launched the M100, a scaled down but fully functioning version of their CMA desktop client. Although the M100 is currently only available for Windows 7 & XP, there is talk of a Macintosh version, which is hovering over the release horizon.  CMA users can pick up the Macintosh version when they purchase a minimum of 50 client licences. The good news is that Polycom are running a  scheme where you can buy 50 licences (mixed PC & Mac) with a generous 50% discount.
So the next time you want to videoconference download the free RealPresence™ app via the apple app store and connect to any standards based video conference.
if you want to connect to more than 1 other  location in the same conference contact and ask for a virtual meeting room, which will give you the ability to connect up to 9 sites in a HD conference plus up to 30 voice calls in the same conference. We believe in connecting people and want you to enjoy the benefits of true collaboration without having to pay a premium.
Happy Conferencing,
Videoconferencing Team

Video Conferencing in courts


Video Conferencing (VC) enables any person who has an interest in court proceedings to be involved in a hearing from a remote location. In its simplest form, a witness at a remote location may give his/her evidence via a video link to the court with one screen and one camera in the courtroom.

The technology needed to establish a video link is relatively simple. A screen and a camera with a microphone is required at each location. Any form of screen can be used. An ISDN telephone line supplied by BT is used to transmit the pictures and sound electronically between the locations. Connection is made by dialling the telephone number allocated to the relevant location.

The Access to Justice Act, 1999 allows VC to be used for civil hearings, e.g. case management conferences, ancillary relief hearings, overseas or remote witnesses or in any civil cases in which the court directs the use of video and the parties involved consent to its use.

The courts listed below have VC equipment and it is possible for every location to connect to any other location on the list. For example, VC equipment in Birmingham can be used to give evidence in a matter being heard in Plymouth. It is also possible for multiple locations to be connected e.g. Bournemouth, Leeds and Manchester can be used to take evidence for a matter being heard at The Royal Courts of Justice in London. The network is extremely flexible.

Video Conferencing now available in Care Centres

To address the problem of delays in child care and supervision cases Video Conference (VC) technology in Care Centres (Care Centres have jurisdiction to hear Public Law Children Act Cases) is now available. The availability of expert witnesses has been identified as one major cause of delay and the VC equipment will provide the courts with greater flexibility for when and how expert witnesses (particularly medical) are required to give evidence.

All 53 Care Centres across England and Wales have now been equipped with mobile VC units and DCA is in the process of developing a national directory of suitable sites at hospitals, medical institutions and universities that could be used by expert witnesses. This means HMCS will now be able to arrange hearing dates and conclude cases more quickly and ensure that the costs to the parties and the public purse will be reduced. It will also mean that experts will have to spend less time travelling to and from court and less time waiting for their case to be heard.

Those wishing to make use of the VC equipment should make their request to the court before the Case Management Conference (CMC) or as soon as practicable before the full hearing. At the CMC itself any necessary practical issues can then be agreed, such as remote location, who will administer the oath and any other special arrangements required to ensure that witnesses are able to give their evidence freely.

Firewall Port Forwarding for H.323 video

H.323 uses a single fixed TCP port (1720) to start a call using the H.225 protocol (defined by H.323 spec) for call control. Once that protocol is complete, it then uses a dynamic TCP port for the H.245 protocol (also defined by the H.323 spec) for caps and channel control. Finally, it opens up 2 dynamic UDP ports for each type of media that was negotiated for the call (audio, video, far-end camera control). This first port carries the RTP protocol data (defined by the H.225 spec) and the second one carries the RTCP data (defined by the H.225 spec).

As per TCP/IP standards, ports are divided into 3 sections: 0-1023 (privileged ports), 1024-49151 (registered ports) and 49152-65535 (dynamic ports). H.323 specifies the dynamic ports in the dynamic range are open. Polycom has added a feature to its product line that allows the ports to use a fixed ports (instead of dynamic ports) so that it can more easily traverse a firewall. Only the system behind the firewall need to turn on this feature, since the firewall will prevent the audio/video/FECC from the outside to come in unless this is enabled.

You must forward the traffic to and from the video endpoint through the firewall using the specified port numbers and protocol types for outgoing calls. To receive incoming calls, your must forward traffic using the 1720 TCP port.

The following are details on port forwarding assignments for various products:

Polycom Port Forwarding

For Polycom products, the following ports must be opened in the firewall and assigned to the IP address of videoconferencing endpoints (e.g. a video endpoint could be at

Port 389 (TCP): For ILS registration
Port 1503 (TCP): Microsoft NetMeeting T.120 data sharing
Port 1718 (UDP): Gatekeeper discovery
Port 1719 (UDP): Gatekeeper RAS (Must be bi-directional)
Port 1720 (TCP) H.323 Call setup (Must be bi-directional)
Port 1731 (TCP): Audio call control (Must be bi-directional)
Ports 3230-3235 (TCP/UDP): Signaling and control for audio, call, video and data/FECC
Port 3603 (TCP): ViaVideo Web interface (ViaVideo users only)
So, a typical H.323 call would use 2 TCP fixed ports (3230-3231) and 6 UDP fixed ports (3230-3235) during the call.

Polycom M100 Desktop Video Software – from Help Book V 1.0 – Specifying Call Settings Preferences: Network NATs and firewalls provide security for your network by limiting outside access to your internal network. Some access, however, is necessary for video conferencing. Therefore, to enable your Polycom Telepresence m100 to freely place and receive calls with the outside world, while still maintaining protection for your network, you must also open ports in the firewall. If your system is on a network where the transmit bandwidth is significantly lower than the receive bandwidth, use asymmetric network to ensure that there is sufficient bandwidth for outgoing calls. To open media ports in the firewall: 1. From the main window, click Menu > Preferences > Call Settings 2. Set the media port range used by the system. 3. Open the same range of ports in your firewall. You must also open these ports in your firewall:

• Port 1718 (UDP): Gatekeeper discovery
• Port 1719 (UDP): Gatekeeper RAS (must be bidirectional)
• Port 1720 (TCP): H.323 call setup (must be bidirectional)
• Port 1731 (TCP): Audio call control (must be bidirectional)
• Port 5060 (TCP and UDP): SIP

Recap of all firewall port configurations for H.323 Polycom video & Network Products

LifeSize Port Forwarding

Login to the Firewall/Router:

Forward port 1720 TCP to the private IP of the LifeSize system.
Forward 2 TCP ports 60,000 and 60,001 to the private IP of the LifeSize system. If you have other services on these ports, you can forward any other 2 TCP ports in the 60,000 – 64,999 range.
Forward 6 UDP ports 60,000 to 60,007 to the private IP of the LifeSize system. If you have other services on these ports, you can forward any other 8 UDP ports in the 60,000 – 64,999 range.
(NOTE: 3 TCP and 8 UDP is the minimum number of ports required for a single point-to-point H.323 video call.)

Login to the LifeSize system:

Go to System Menu –> Administrator Preferences –> Network –> NAT
Enable Static NAT, and enter the public IP address of the firewall in the "NAT Public IP Address"
Go to System Menu –> Administrator Preferences –> Network –> Reserved Ports.
Enter the TCP & UDP port range you chose in the steps above.

Tandberg Port Forwarding

"In order to properly support a NAT configuration, the firewall will need to be configured as a one-to-one relationship between a public IP address and the private IP address for all ports in the H.323 range (which include 1718 UDP, 1719 UDP and 1720 TCP as well as other vendor-specific TCP and UDP ports needed to complete H.323 calls). For the specific range needed, consult your endpoint manufacturer."

Polycom GMS Ports:

21 (FTP) – Software Updates & Provisioning
80 (HTTP) – Pulling ViewStation/VS4000 info
3601 (Proprietary) (Data Traffic) – GAB data
3603 – TCP – Pulling ViaVideo info (since might be non-web server PC)
389 (LDAP and ILS)
1002 (ILS)
GMS listens for connections on ports 80 and 3601 (GAB) and in the future will listen on port 3604 (ViaVideo) and other potentials later.

H.323 Ports (IP based video conferencing):

80 – Static TCP – HTTP Interface (optional)
389 – Static TCP – ILS Registration (LDAP)
1503 – Static TCP – T.120
1718 – Static UDP – Gatekeeper discovery (Must be bidirectional)
1719 – Static UDP – Gatekeeper RAS (Must be bidirectional)
1720 – Static TCP – H.323 call setup (Must be bidirectional)
1731 – Static TCP – Audio Call Control (Must be bidirectional)
8080 – Static TCP – HTTP Server Push (optional)

1024-65535 Dynamic TCP H245
1024-65535 Dynamic UDP – RTP (Video data)
1024-65535 Dynamic UDP – RTP (Audio data)
1024-65535 Dynamic UDP RTCP (Control Information)
These ports can be set to "Fixed Ports" on Polycom systems, as opposed to dynamic.

Other Polycom ViewStation Ports:

21 (FTP) – Software Updates & GMS Provisioning
23 (Telnet) – For Diagnostics & API Control
3220 to 3225 – TCP Ports
3230 to 3247 – UDP Ports
Other ViaVideo Ports:

3604 (GMS Server Discovery) (Used by ViaVideo) (Broadcast)
Accord (Polycom Network Systems) Additional Ports:

5001 – Static TCP – MGC Manager (5003 can be chosen instead within MGC)
21 – Static TCP – FTP (retrieve MGC config. Files etc.)
RADVision Additional:

1820 – Gateway Signaling/Call Setup
2720 – MCU Signaling/Call Setup
d-Link DVC-1000 Ports:

The port 1720 (TCP) and the 6 ports 15328-15333 (TCP and UDP) need to be forwarded. d-Link indicates that NetMeeting and the H.323 cannot co-exist behind the same router simultaneously.

And finally after you install the software read “How to start video conferencing on a budget


London based BAA Chief Executive Colin Matthews was unable to connect his Polycom video conference system to a video conference meeting held at the Waldorf Astoria Hotel New York. BAA’s incumbent service provider simply could not connect the long distance UK IP based video conference to the New York ISDN video conference call. BAA’s Technical Advisor Paul Hayley was delighted when Video Conferencing London were able to connect the two sites with their on demand video conferencing bridging service.

Technical Director Mark Williams said “ Our on demand video conferencing bridging service is the mobile phone of the video conferencing world. We simply give businesses large and small access to the same video conferencing facilities that almost all large organisations currently use every day.
Not only can we connect different video conference systems together, if you can connect your PC to a broadband connection you can connect to any Polycom, Tandberg, Sony, or Life-size system.
We believe that if small businesses are to survive and indeed get to play with the big boys, they will need to adopt tools like video conferencing that will not only give them access to the people sitting in big board rooms but will also help them communicate internally.
Video Conferencing London is a privately owned certified supplier of video conferencing products and services.

If you have an IP video conferencing system you can use our bridging service, which is commonly known as video conferencing bridging, to connect to ISDN video conferencing systems. In fact, you can connect to any manufacturer’s video conferencing systems including Polycom, Tandberg, Sony, and Lifesize. That’s not all. You can connect to up to nine sites (you plus eight sites) in a mixed video conference call (IP & ISDN), share your desktop applications (collaboration), record your conference and stream your recording to up to 2000 users who log in to your password protected stream.

What exactly are we offering?

If you take away all the jargon and fan fair, what we are offering is the ability to connect your PC or Video Conferencing system to any PC or Video Conferencing system. While you’re connected you can record, then stream the recording or stream the session live. What is not simple is the diverse number and types of applications that this opens up. Take for instance the Chairman of BAA who found himself unable to connect his IP based Polycom video conference system to an ISDN based system at the Waldorf Astoria Hotel in New York. He had a meeting scheduled within the hour and his incumbent provider could not connect the call. Within twenty minutes of speaking to our engineers, BAA’s Engineers were able to give the Chairman the green light for his scheduled call. A North London Student, who in order to graduate from her PhD course had to deliver a presentation to examiners at her university in Singapore, found out that the cost to hire video conferencing was more than she had, so she had to find a far cheaper alternative or face losing her PhD. She was amazed when she found out that she could use her PC to connect to the Polycom Viewstation in the university’s grand lecture theatre; more importantly she paid 60% less than the amount quoted by even the most basic providers. And for those of you who are wondering what happened . . . she got her PhD. We always have time for those who are running late and consequently cannot make the video meeting on time. We simply tell them to use their mobile phone to dial into the meeting where they can hear everything that is said and more importantly contribute their expert opinion.
What’s in the box?

The key to explaining technology to non technical people is to show them how it solves their problem. You don’t need to know what’s in the box, unless of course there is nothing in the box . . . well, there’s nothing in the box. What you get is a virtual key to your own virtual room which is located on our very real video server.

To use an analogy, imagine you have very high spec video conference system, the type that you would usually purchase for around £150,000, well that is exactly what you have access to, and that is what gives you the ability to connect to almost any video conference system, using your PC. Make good decisions faster.

If you were a baby boomer you may remember a time when the only way to make a phone call was to run 2 miles down the road to the nearest BT phone box. 60 years on do you now think video conferencing is just as inaccessible as phones were back then? The age were business class video conferencing is in the palm of your hands is not yet here, however the speed in which business is conducted dictates that to be efficient, effective and profitable we need to communicate often and well, so that as business people we can make good decisions faster than our nearest competitor.

I agree that there are lots of great products out there that will keep you connected; however there is only one product that doesn’t require any capital expenditure, long term commitment or organisational membership. Our ‘on demand’ video conferencing service really is available on demand. All that we ask is that PC users have a webcam, headset and mic with a fast broadband connection, and video conference users continue as usual.

If you don’t have a video conferencing system and are interested in using your PC to connect to any ISDN based video conference get the free trial version today. If you have video conferencing already and want to connect to a IP or ISDN system connect to our bridge today.

This guide should help you start asking questions of the business needs for video conferencing, and indeed choose the best infrastructure to meet you conferencing requirements.

Network Infrastructure
One of the first things companies should consider when choosing video conferencing is the type of network they want to run the video packets over. There are typically two ways to video conference which are video over ISDN or video over IP.

Video Over ISDN
ISDN is the traditional method used for video conferencing. To video conference over ISDN you will require between 2 and 4 ISDN2 lines. (ISDN30 in 64k format cannot carry video packets unless your PBX can ‘bond’ two lines in 128K pairs – this can often be done using an s-bus card that plugs into a PBX, however each PBX manufacturer may do it differently.)
When considering using ISDN for video conferencing you need to weigh up two things:

1) Cost
2) Packet loss/Stability
1) The cost to install ISDN lines is typically £249 per line. There is a monthly line rental charge of about £24 per line. A typical installation will consist of between 2 and 4 ISDN lines. Call charges associated with using ISDN lines may vary depending on your provider. We provide ISDN lines at wholesale prices to ensure customers can benefit from rates that are typically 80% below those of BT retail (see article).

A typical one hour UK to US video call will cost around £18: a UK to national call will cost about £6 per hour.
2) ISDN is the traditional method for video conferencing and it is still predominately used by many organisations. Since video packets over ISDN do not travel along the same exchange as IP packets (internet Protocol) the risk of the ‘bottle neck’ effect is eliminated and all packets sent from the far end site arrive at the near end site quickly and in the correct order. (Packet loss occurs when video packets do not arrive in the correct order which can cause the image to freeze or become blocky.)
Video over ISDN is in most cases the most stable way to video conference. It is worth noting that ISDN based video conference systems require a bridging facility to communicate with IP based video conference systems and vice versa. We offer full managed and unmanaged bridging facilities.

Video Over IP
Video conferencing over IP is fast becoming common place in organisations. There is one overwhelming reason for this change: that is the cost to increase IP bandwidth capacity has been falling and still continues to fall.

There are 3 main levels of service (DSL, ADSL, SDSL) available which offer different quality of service and bandwidth capacities, with DSL being the lowest and SDSL being the highest.
We recommend SDSL for video conferencing. Most companies have some internet connection and can run video conferencing without upgrading. We usually advise companies considering using video conferencing over IP to look at their network usage over the past 12 months and consider future increases/decreases and operational changes that may affect bandwidth usage. Each case may vary depending of usage but as a rule of thumb we recommend a provision of 1.5Mbps to 2Mbps be set aside for video conferencing.

The stability of a video conference over IP is dependent on many networking factors including size and stability of bandwidth for both yours and the far site’s network. For more information about video conferencing over IP please contact one of our networking specialists.

There are no call charges associated with using video over IP, unless you connect to an ISDN based video conference system. You will be charged for connection to an ISDN gateway; typical ISDN gateway connection charges range from £60 – £160 per hour depending on level of service, connection speed and operator.

Bandwidth Requirements – now & in the future
For both IP and ISDN networks you will need to consider who you will be conferencing with on a regular basis. Ideally you will have the same type of network as other sites within your group. We provide bridging services to allow you to conference with IP from ISDN and vice versa.
Once you have decided on your network you will need to consider what features you want from a video conference unit.


Hardware Functionality
In general there are only really two add on options to consider: Multi Point capabilities (connecting with you plus two or more sites) and People & Content (sharing presentations, PowerPoint, spreadsheets etc. within the conference). Since systems ship with the ability to share presentations IP to IP multipoint upgrade is often the only choice.
