Figure 79. The Codec Preference setting
Codec Preference - Incoming Calls
When the Codec Preference feature is enabled, the system uses the following logic for handling incoming calls,
based upon the content of the first SIP INVITE request.
Preferred Codec G.729
First SIP Invite Request Content Codec Used for the Call
SIP Trunk supports G.729
The IP Codec table of Enterprise Manager is ignored. The
system uses codec G.729 to negotiate with the endpoint.
SIP Trunk does not support G.729 No codec is enforced.
Preferred Codec G.711 Mu-Law
First SIP Invite Request Content Codec Used for the Call
SIP Trunk supports G.711 Mu-Law
The IP Codec table of Enterprise Manager is ignored. The
system uses codec G.711 Mu-Law to negotiate with the
endpoint.
SIP Trunk does not support G.711 Mu-Law No codec is enforced.
If the target extension or DNIS number is enabled for Fax-Over-IP (FoIP), then no codec is enforced.
Codec Preference - Outgoing Calls, Third-Party IP Phones
When the Codec Preference feature is enabled, the system uses the following logic for handling outgoing SIP
trunk calls from third-party IP phones. (Calls are considered SIP trunk calls if the target has a SIP trunk access
code or an outcall routing access code prefix.)
Preferred Codec G.729
First SIP Invite Request Content Codec Used for the Call
Supports G.729
The IP Codec table of Enterprise Manager is ignored. The
system uses codec G.729 to negotiate with the endpoint.
