Hi Daniel
You may want to kill me but I'll be honest, I'm actually using kamailio's
1.5 UAC module on an Opensips 1.6.2 :$ so I don't know if the problem
could be related to that. Anyway, here is the bad register message when
using only $uac_req(ruri)="sip:8.14.80.37:5061". Note that the SIP part
itself its correct, but the UDP destination port is wrong:
Internet Protocol, Src: 8.14.80.16 (8.14.80.16), Dst: 8.14.80.37
(8.14.80.37)
User Datagram Protocol, Src Port: sip-tls (5061), Dst Port: sip (5060)
C%E@@PP%
REGISTER sip:8.14.80.37:5061 SIP/2.0
Via: SIP/2.0/UDP 8.14.80.16:5061;branch=z9hG4bK9b35.3e435b31.0
To: sip:LV-SKRUPPA at 8.14.80.37
From: <sip:LV-SKRUPPA at 8.14.80.37>;tag=a649c0188a5a7b7f4a4dfeaea88004c3-b5bd
CSeq: 10 REGISTER
Call-ID: 52d42e13484b4229-29572 at 8.14.80.16
Content-Length: 0
User-Agent: OpenSIPS (1.6.2-notls (x86_64/linux))
Contact: <sip:LV-SKRUPPA at 8.14.80.16:5061>
Expires: 60
I hope this can be of any help.
Kind regards,
