[cisco-voip] iLBC and Gateways

[Ryan Ratliff]

I suspect H.245 doesn't support iLBC (yet).

Looking in the ASN description from http://www.packetizer.com/ipmc/ 
h323/standards.html the latest H.245 version doesn't seem to list iLBC.
I could be reading it wrong though...

I checked the SRND for CUCM 7.x Ilbc is not listed as a supported  
codec there either.

Got this to work with a MGCP gateway. Had to add/do the following:

mgcp codec ilbc
ccm-manager mgcp codec-allno mgcp mgcp Still can not negotiate using  
H323, opened a TAC case, will post fix when I get it. Steve

What type of gateway is it? If H.323 make sure iLBC is either set on  
the voip dial-peer or in a codec class applied to the dial-peer.

If MGCP check out http://www.cisco.com/en/US/docs/ios/12_4t/12_4t15/ 
it_amrnb.html.

Doing some testing with iLbc. I can place a call from IP phone (7962)  
to IP phone 7962 using iLbC and 7962 to IP Communicator 7 and I see I  
am using the iLBC codec on each end of the connection. I negotiate  
G729 when I use a gateway to reach the PSTN. Far as I can tell all is  
set up correctly with my regions, locations, device pools etc. Is  
iLBC supported in the following path between the phone and gateway?
7962 --IP------2851-------PRI-------PSTN
Gateway is running 12.4.20T and CUCM is 6.1.1
Thanks
