MCUs

Look at Radvision...

I would like more information about this

Each MCU of the market has its own pros and cons, say price at least :-) It is a matter of

- scale (how many parties, how much bandwidth, growing perspectives)

- connectivity (IP ISDN Voip 3G/UMTS

- features (splitscreen, data interaction/presentation, recording)

- administration (adhoc , participant driven, specialist driven, service provider accounting)

Hidden quality factors like

- amount of interoperability problems with particular conferencing systems

- common protocol options (H.235,H.239,H.264,...) are always work in progress and may decrease with newer releases and increase with changes inthe endpoints

So I suggest to have a look on the conferencing systems involved too

I started out looking at

Cisco is a OEM of Radvision

Yes, nice for high performance IP-only self-running conferences poor web interface, but this may change ...

Polycom MGC-25 > older stuff, there is a new series available

Tandberg MCU (which appears to

you have to pay for a gateway anyway. Do you need ISDN ? Tandberg and Polycom are expensive and build for service providers mainly.

This requires a appropriate scheduling/web interface, Do you like to build a central service ? Fixed group of targets or arbitrary future customers ?

a video-based

I suggest to have a look on DST media, which is market leader in Asia (joined with Polycom last year)

DST`has a nice recorder unit offering playback on demand As DST is the direct competitor of Codian, I exspect Codian has a comparable solution :-)

Completing the list: Radvision VCON Both come with a software-only client VCON has the leading management system called MXM. This offeres user driven telephony-like switching, central management includes foreign endpoints too. (Tandberg and Polycom do support their own endpoints mainly)
