Is the 200 getting back to the carrier? I’m assuming not. What does the INVITE and 200
message look like

Kamailio.
Here is the situation. Call arrives from voip provider to kamailio, it dispatches to
asterisk, asterisk answers, and initiates another call through kamailio, and the voip
provider.
K <-----------> Asterisk
Invite ->
<--- 100
<----180
<--- 200
<--- 200 retransmission,; happens 3-5 times
Invite --> (same callid & cseq)
<--- 200 retransmission,; happens 3-5 times
So, we see the asterisk dialplan has answered, and another call is placed form the
asterisk
K <-----------> Asterisk
<------Invite
100 ---->
(2 or 4 seconds later)
408 ---->
both nodes (kamailio and asterisk) show the same traces.
Any ideas would be greatly & truly appreciated, I am getting quite desperate about
this one !

Are you getting the 408 from Asterisk or Kamailio? Perhaps you can provide a snippet of
a sip capture.

Hi Jean,
It might be something else. We do have an entire virtualized environment on Vmware with
Asterisk, kamailios and another VoIP component without any issue with thousands of
customers using it.

Hello
We are running a kamailio 5.0 on a VMWARE / VSPHERE 6.0 vm, with a couple of asterisk
running on 2 physical hosts.
Audio goes straight to the asterisk, no rtpengine / rtpproxy. I actually have no audio
issues, but communication between the asterisk & kamailio for sip sometime fails - I
get a few 408. I cant tell if this is network related or virtualisation related.
Anyone has advice on kamailio on a VM, when it only handles sip ?
