Does RFC 2543 take care of the scenario when the SIP gateway has to alert the caller upon receipt of inband alerting tones from a PSTN switch (after ACM is received) because in this case sending the corresponding SIP 180 ringing response would not establish an RTP media session which is required even before 200 OK is received. -Gaurav _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
