Known Affected Releases
Symptom: causing the SIP A Side to send Bye as it does not receive the Re-Invite for any changes in parameter initiated by SIP B Side . Conditions: On a SIP to SIP call going over two PGWs with E-ISUP in between, post the call establishment, B-side sends a Re-Invite which contains no SDP offer to the out bound PGW. This PGW-01 sends E-ISUP notify to in bound PGW (PGW-09). But this PGW-09 does not send any re-invite out to A-side.
