Hi,
I have integrated CCM 4.0(1)(with latest patches) with cisco SIP Proxy server 1.3 of the service provider.I am able to make in bound & outbound calls & the codec I am using is 711ulaw on SIP trunk . I have configured the phone for G711.
1.SIP Trunk config on CCM has only two codec options ie 711ulaw & 711alaw.But as G711 uses more bandwith(around 80K).Is there any way I can configure G729?
2.Also the call is getting disconnected exactly after 80 sec.Is there anything to be configured on CCM.
3.If I want to place CCM behind the firewall(PIX) what are the changes to be done on PIX.
4.Is there any issues If I configure NAT for CCM servers & IP phones.Can I configure PAT on pix or interner router for ip phones.
