[Sip-implementors] How to stop CDR?

[Sushil Kumar Verma]

Hi all, Can somebody help me find the solution for the following question. How to stop the CDR (billing) if one of the SIP phones unplugs the ethernet cablewhile in conversation. If we wait for the other party to hang up, the delay may not be acceptable particularly if it is a long distance call (PSTN interworking) or the other user can also unplug it or can just leave the phone off hook. Is it advisable for Proxy to send some message (NOTIFY, OPTIONS etc.) at regular interval and expect 200 OK?   Regards, Sushil Kumar Axes Technologies (I) Pvt.
