Prerequisite features

Determine Call Type Feature

The Call Parties Address Determination feature is a pre credit check feature early in the feature list (but always after the emergency number feature). The feature attempts to extract the called and calling parties addresses from the INVITE and set the ‘CallingPartyAddress’ and ‘CalledPartyAddress’ session state fields. The feature analyses the relevant ‘InviteRequest’ on the ‘callingParty’ leg and the ‘calledParty’ leg (the latter only being used in the third-party-triggered case when determining the called party address).
