Re: [Sip] When is a 487 Request Terminated is sent?

Consider the following scenario: (A) is inviting (B):

1. (A)--------------------INVITE --------------------->(B)
2. (A)<------------------180 RIGING------------------(B)
3. (A)--------------------CANCEL------------------->(B)
4. (A)<------------------OK----------------------------(B)
5. (A)<---------487 Request Terminated-----------(B)
6. (A)--------------------ACK------------------------->(B)

OK (4) reply corresponds to the CANCEL (3) request.
487 Request Terminated (5) reply corresponds to the INVITE (1) request.

Bobby Sardana.
