If one of the other NetPro's would like to step in and correct me, please feel free.

In call manager 4.1(3) you have very limited SIP support and only via trunk). The configurable parameters for SIP (in CCM 4.1(3) are found in Service > Service Parameters > Cisco CallManager Service (from the Service drop-down list). Most every configurable setting there is for counts and timers (retry and other).



I have connected Cisco CM 4.1(3) to another IP-PBX(Different Vendor) through SIP trunk.Now how do I send G711A,G729 and G723 codecs through the trunk to the IP-PBX which supports all the codecs.Also, If the IP-PBX sends G723 or G729 algo's in INVITE, etc.,then how the Cisco CM will reply with either G729 ro G723.Pls help
