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....:(
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,
Hope it helps,
Samuel.

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.

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
