Hi, sure. That's why it's called "transaction oriented". On a SIP-Theory basis, the second INVITE opens a new transaction!! For correlation the Call-ID keeps the same! This is how all of the big carriers I know handle OverlapDialing.
The problem is: * I am receiving an INVITE. * At this point I don't know if there will be a second INVITE or not. So I have to wait. * If the timer elapses, ok handle this INVITE. * But if there IS a second (third..) INVITE, I have to cancel the first and then handle the second. Sounds like nobody has done this before... any suggetions appriciated. greetz Am 04.02.2014 15:56, schrieb Alex Balashov: > Indeed, Section 3.1 in the referenced RFC covers this pretty well. > > On 4 February 2014 09:47:38 GMT-05:00, "Olle E.
