Hi Bogdan, I'm looking for the ability to selectively remove codec advertisements from the SDP. For example, if my customer sends a call to me for PSTN termination he may advertise G711 and G729, with G711 preferred. By looking at the number of existing dialogs I may know that he's running low on bandwidth, so I would like to suppress the G711 advertisement ultimately causing a 200 OK from the carrier with G729.
Generically, in this application we're looking only to suppress G711 at certain times. I understand normally codec selection is done completely by the gateway device. However, my gateway devices aren't smart enough to take bandwidth utilization into consideration when choosing which codecs to advertise. I'm hoping my proxy might be. :) Does that make sense? - Jeff On 1/29/09 5:04 AM, "Bogdan-Andrei Iancu" <[email protected]> wrote: > Hi Jeff, > > right now there is only available some functionality to check the codecs > (to see what codecs are advertised in the SDP)...
