Nope...not in this case. Here, the originating UA sends one INVITE. My SER is sending the multiple INVITEs before it even receives a 100 Trying from the far end. It does not happen on every call...there seems to be no pattern as to when it does happen.

Thanks.

The originating UA may be where to look.

Sometimes my ser proxy resends an INVITE 67 milliseconds after the original INVITE without receiving any response from the recipient. Essentially, what would normally be a 1 second timer for a resend is vastly shortened with no real explanation. If there is a Trixbox at the other end, the conversation results in a dropped call as the Trixbox continues to send repeated 200 Oks, but does not acknowledge the ACKs to those messages.

The Asterix supposedly has a fix for this issue that is not included in the Trixbox.

What I am trying to determine, though, is WHY the double invites are sent in the first place.

Thanks,
Steve
