Cancel dialog after do_invite

[adamchol]

Idk if I'm missing something but is it impossible right now to cancel the INVITE (when user "hangs up" before the other side pick up) after calling DialogLayer::do_invite? Do I have to manually do something like the implementation of the do_invite, or somehow maybe take the state receiver, wait for state update and then lookup the dialog and cancel it?

I'm trying to figure out the intended API here, can someone guide?

No, you need not manually do anything.

When the future created by do_invite was dropped, it will auto hangup/cancel.

You need to polling the state receiver only when you have to waiting for some STATE. like 100 Trying/ 180 RingRing received.

For final response like 200, 4XX, 6XX, the do_invite will complete.

#75 intent to waiting for the response to INVITE in the drop, it does not trying to change the API. Current sip flow is like this:

INVITE -> 
<- 100 Trying
// guard dropped
CANCEL ->
<- 200 to CANCEL
<- 487 to INVITE  (waiting for this)
ACK ->

That fix the Terminate State was not generated when client CANCEL.
