[SR-Users] ACK to 200 OK discarded by loose_route()
SIP Mailing-list
sip at racitup.com
Fri Apr 6 17:16:36 CEST 2012
Hi guys,
Hope someone can help me with this.
The background: I'm just trying to implement a simple load balancer with
one source and multiple destinations using the call load balancer (ALG10)
in dispatcher. kamailio version 3.2.0
The symptoms: I have a simple script working in one test environment
(csipsimple -> kamailaio -> Twinkle) but can't get it to work in another
(Dialogic HMP 3.0 -> kamailio -> Dialogic HMP 3.0)
The details: I've done a debug trace (below) in both environments and can't
see the problem. For some reason the ACK is destroyed before it is
forwarded even though the log says "[forward.c:601]: Sending:#012ACK..."
Any help would be much appreciated!
TIA,
Richard
