I have a question regarding cancelling a call:
according to RFC 3261, you cannot send a CANCEL request, as long as
no response (1xx or 23456xx) has been received for an outgoing INVITE.
after my app called eXosip_call_terminate, any following response
cannot be assigned to a SIP call.
but if the INVITE request / 100 Trying response just took quite long
to the callee and back, shouldn’t the caller send a CANCEL/BYE in case
he receives a late response for an already cancelled outgoing call ?
