Author: Anca Vamanu <[email protected]> Committer: Anca Vamanu <[email protected]> Date: Fri Jan 11 11:50:26 2013 +0200 dialog: fix bug when detect_spirals enabled If detect_spirals enabled and the caller sent an Invite which received a negative response and then immediately sent another Invite with the same callid and tag, the module did not create a dialog record for the second Invite. It wrongly concluded that the Invite is spiraled. This resulted in missing CDR for that call. Behavior observed if the first Invite has a small Session-Timer interval and receives a 422 reply. When the phone sent the second Invite with a larger Session-Timer, which could have been successful, it was not recorded by the dialog module.
