There are few corner cases with timers in SER version 0.9.6 that may cause this double immediate resending of the initial INVITE. I'm sorry but I don't remember the causes....:(<br><br>What I can tell you is that SER
2.0 has a completely recreated timer structure that should solve this issue, if you can test and provide feedback, it would be really appreciated,<br><br>Hope it helps,<br>Samuel.<br><br><div><span class="gmail_quote">2007/6/22, Stephen Helfen <

<div><div style="text-align: left;">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.

The originating UA may be where to look.<br>

<div style="text-align: left;">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.<br>
<br>
The Asterix supposedly has a fix for this issue that is not included in
the Trixbox.<br>
<br>
What I am trying to determine, though, is WHY the double invites are
sent in the first place.<br>
<br>
Thanks,<br>
