Using Cisco 3526 IPVC for Voice Calls as well

[andy-smith]

Does anybody know the latest capabilities of the Cisco 3526 gateway when used as a Voice gateway? The Cisco SRND for "Cisco IP Video Telephony", which was published in July 2004, states that the IPVC gateways do NOT support H.245 Empty Capabilities Set or H.450. So they will give you supplementary services such as Hold, transfer, etc. Version 3.0 of the 3526 documentation lists "Empty capability set support" as a feature, although it does not state H.245 or H.450.

Basically, I want to use a 3526 as a second Voice gateway as well as a Video gateway in a Call Manager deployment. I am just concerned that I won't get all the supplementary services when using it for voice calls.

Any input would be greatly appreciated.

I know the product can support voice, my main concern was the support for ECS (Empty Capabilities Set) within H.245. If it does not support this my IP Phones will not be able to use the supplementary features such as Hol;d, Transfer, etc,etc.

I have escalated this to Cisc here in the UK for clarification. I am sure it will, but I just want clarification from Cisco or somebody that has used it in the same scenario.
