Hello List.
I’m testing the last kamailio versión 1.5.3. I’m using the default configuration file and a gateway sending calls to a registered device.
U 10.0.0.11:5060 -> 10.0.0.7:5060 SIP/2.0 200 OK. Via: SIP/2.0/UDP 10.0.0.7:5060;branch=z9hG4bK894be985a441. Record-Route: sip:10.0.0.11;lr=on. From: sip:3341876@10.0.0.7;tag=894be985a4. To: sip:5501234567@10.0.0.11;tag=3079903260. Call-ID: 892a1d4b-35e7-e926-8085-0002a401f510@10.0.0.7. CSeq: 41 INVITE. Allow: INVITE, ACK, CANCEL, BYE, NOTIFY, REFER, OPTIONS, UPDATE, PRACK, SUBSCRIBE, INFO. Allow-Events: talk, hold, conference, LocalModeStatus. Contact: "5501234567" sip:5501234567@10.0.0.20:5060;transport=udp;+sip.instance="urn:uuid:00000000-0000-1000-8000-00085D1B6C7A".
The proxy sends a correct Contact header to the gateway.
U 10.0.0.7:5060 -> 10.0.0.11:5060 ACK SIP/2.0.
The gateway sends a broken RURI.
--> The gateway (or any transparent component between the proxy and the gateway - e.g. a SIP firewall) is broken.
Maybe the GW gets confused by the GRUU parameter included in the contact header.
