I would be curious to know the circumstances in which a receiving peer is sending a 487 and what the justification for that would be. A 487 is usually a response code to verify receipt and execution of a CANCEL transaction from the other side.

I think what I meant to imply there but did not say is that Asterisk considers this a bizarre thing for an endpoint to do as a final response to an INVITE (let alone one which has already been picked up with a 183) and understandably produces its preferred feedback to the calling leg for all bewildering situations -- 603.

Hi All, Have any way to asterisk forward the 487 Request Cancelled in SIP TO SIP call? In a SIP to SIP call when the called peer B send 487 to Asterik, Asterisk return to calling peer A 603 PEER A ASTERISK PEER B | INVITE ------------>| | |<------------TRYING| | | | INVITE------->| | |<-------TRYING| | |<------------183| |<-----------------183| | | |<------------487| | |ACK----------->| |<-----------------603| | |ACK---------------->| | -------------- next part -------------- An HTML attachment was scrubbed...
