  • Call looping prevention
    Publication number: 20040028032
    Abstract: A method of transferring signalling information from an SS7 network to an IP network using SIP signalling through a Media Gateway Controller (MGC), the method comprising receiving an Initial Address Message (IAM) from the circuit switched network at the MGC, and generating a SIP set-up message at the MGC, wherein the SIP set-up message includes a loop protection field containing a hop counter or redirection counter in the IAM.
