If a policy response contains a profile name and a locally configured profile

exists with the same name, SBC applies the same

profile.
If a policy response does not contain a profile name or if the profile name does not match with any local profile, SBC applies the local Cause Mapping profile attached to the SIP Trunk Group
...
(if
...
configured).
SBC applies a default profile name if none of the above two cases match.
The following new IPSP configurations are added to PSX under SIP Cause Mapping section:
