How do I interconnect ISUP (SS7 signaling) and SIP? sagitraz 27-June-2008 03:51:07 PMComments Its basically SIP to facilitate the interconnection of the PSTN(SS7) with IP. This is intended to allow traditional IN-type services to be eamlessly handled in the Internet environment. It is essential that SS7 information be available at the points of PSTN interconnection to ensure transparency of features not otherwise supported in SIP. SS7 information should be available in its entirety and without any loss to the SIP network across the PSTN-IP interface. SIP-T defines SIP functions that map to ISUP interconnection requirements.

Interconnection Requirements SIP Functions Availability of ISUP information Encapsulation of ISUP in the SIP body Routability of SIP messages with ISUP dependencies Translation of ISUP information into the SIP header Transfer of mid-call ISUP signalling messages Use of INFO method for mid-call signalling Posted by snjysanjay05 |
