How to Collect CPC Parameter Value From SIP URI of P-Asserted-Identity or MIME Body

Use the following procedure to collect the CPC parameter value from the SIP URI of a P-Asserted-Identity or a MIME body (in a SIP-I scenario).

1. Enable the flag callingPartyCategoryInterworking in the NNI Profile object for the SBC to fetch the CPC parameter value from SIP URI of P-Asserted-Identity or from MIME body (in SIP-I scenario) on the ingress side of the trunk group:

   % set profiles signaling NNIProfile <NNIProfile_Name> callingPartyCategoryInterworking <disabled | enabled>

2. Disable the flag enablePCVTTCParams in the NNI Profile object to avoid activation of NNI PCV feature:

   % set profiles signaling NNIProfile <NNIProfile_Name> enablePCVTTCParams <disabled | enabled>

3. Enable the flag cpcInterworkingForNNI under Sip Trunk Group - Signaling object to populate the CPC parameter value in SIP URI of P-Asserted-Identity on the egress side of the trunk group:

   % set addressContext <addressContext_Name> zone <zone_Name> sipTrunkGroup <sipTrunkGroup_Name> signaling cpcInterworkingForNNI <disabled | enabled> 

Example:

set profiles signaling NNIProfile NN1 callingPartyCategoryInterworking enabled
set profiles signaling NNIProfile NN1 enablePCVTTCParams disabled
set addressContext default zone default_zone sipTrunkGroup SipTrunkGroup1 signaling cpcInterworkingForNNI enabled
