View Full Version : Tandberg 16+16 not working with LifeSize

Hello All,

This is the first time I've posted on this site so please bear with me if I don't give all the information needed.

The problem I'm having has to do with a new LifeSize room endpoint connecting with a Tandberg 16+16 MCU. The calls are IP and the LifeSize does an initial connection with the Tandberg MCU and then sits in the connecting state for about 2 minutes until it eventually times out and drops. The same thing happens when the Tanberg MCU calls the LifeSize room. I can call any endpoint I've tried with success from the LifeSize but cannot connect to the Tandberg MCU.
The techs at LifeSize have analyzed a dump from the failed calls and tell me the Tandberg is only offering H.261 video which the LifeSize does not support. My guy that runs the bridge says they have H.264 enabled but it (and H.263) never seems to get offered to the LifeSize. Anyone have any ideas on what could be causing this?

What version of software is on the LifeSize and what version on the TANDBERG MCU? Give me the info and we will try it here.

Sean,

The Tandberg is running D3.10 and the LifeSize is running version 3.0.

Thanks

I tried this here and it works fine, H.264 CIF.

Make sure you do not have 'legacy mode' turned on in the conference:

Legacy mode will remove all decodable codecs from the cap set except H.261 and G.711 for (ironically) maximum interoperability.

Sean,

Thank you, thank you, thank you. I've been beating my head against a wall for 2 weeks now and your answer was right on the money. As soon as my bridge guy unchecked the legacy mode box we connected perfectly using H.263. I really appreciate your help.

Thanks,
Paul
