#1166 closed defect

Detection of offer/answer glare condition — at Version 2

Description (last modified by bennylp)

The pjsip_inv_session() happily returns 200/OK to UPDATE/re-INVITE request even when it has sent an offer and hasn't received final answer yet.

Scenario:

  1. Send UPDATE
  2. Receive INVITE
  3. We send 200/OK

PJSIP should send 491 (Request Pending) for the incoming request in the last step above.

Note that had we received UPDATE in Step 2 above, we will correctly respond with 491.

See also #1169 (Automatically retry the re-INVITE or UPDATE request upon receiving 419/Request Pending response)
