Symptom: SIP to SS7 call hung. Conditions: PGW do met hung call issue while receiving the CANCEL. The case is quite strange and abnormal. According to spec, pgw will wait for ACK after 200 OK(INVITE) is sent, but before the ACK is recevied, TCC SS7 released the call. And still before the ACK for 200(OK) INVITE is recevied, a CANCEL is recevied on OCC. PGW did not Release the call on receiving CANCEL and send no response to CANCEL.
