Description:
The IMG supports SIP to ISUP and ISUP to SIP Interworking that complies with RFC 3398 (ANSI) and Q.1912.5 (03/2004) (ITU-T). The object below is used when configuring SS7 to SIP interworking. If configuring SIP to SS7 interworking, refer to the IMG 1010 - Interworking from SIP to ISUP topic. The SIP ISUP IW object configuration allows a customer to decide what message is sent upon receipt of the 183 Session Progress message if they don't want to follow the rules according to RFC 3398 or Q.1912.5 (03/2004) (ITU-T). Use the information below to decide which type of mapping/interworking will be applied.
