Thanks, Jan....
1. When you say the BYE is missing the Route header field of ser, I'm not
sure I follow.
The BYE from our softswitch (packet 17) looks like this..
BYE sip:6037534033 at 10.16.1.218 SIP/2.0
Via: SIP/2.0/UDP 172.17.4.102:5060;branch=z9hG4bKSNCLLC1070017565
From: <sip:6032251114 at 10.16.1.147:5060>;tag=1069363200-4210481069784248-11
To: 6037534033 <sip:6037534033 at 10.16.1.147:5060>;tag=5c948a53eb3c31b
CSeq: 53 BYE
Call-ID: e543c536ae93df9befd8b930046bbda3 at 10.16.1.147
Max-Forwards: 10
Route: <sip:6032251114 at 10.16.1.147:5060;ftag=5c948a53eb3c31b;lr>
Content-Length: 0
Is this part not correct? ==> Route:
<sip:6032251114 at 10.16.1.147:5060;ftag=5c948a53eb3c31b;lr>

Hello,
there are two problems:
1) BYE sent by the softswitch is missing Route header field of ser.
2) You configuration script should contain t_relay() as the last
command. Without that it will drop all requests that don't have IP or
domain of SER server in the Request-URI which probably isn't what you
want.
BTW: The message below is an excellent problem report ! It contains all
the necesarry information in clear form and it is quite easy to quickly
locate the problem.
