Hi, I have presence in OpenSer same box. modparam("presence","server_address","sip:85.92.0.210") I've a problem because I get "in-dialog" SUBSCRIBE messages without "Route" header: When my SIP client (Twinkle or X-Lite) starts up it sends a SUBSCRIBE NOT-in-dialog: ---------------------------------------------------------------------------------------------------------- # U 2007/09/10 17:54:08.294012 222.21.235.18:5060 -> 85.92.0.210:5060 SUBSCRIBE sip:ibc@sip.domain.net SIP/2.0 Via: SIP/2.0/UDP 192.168.1.58;rport;branch=z9hG4bKcsmbires Max-Forwards: 70 To: <sip:ibc@sip.domain.net> From: "Angel" <sip:angel@sip.domain.net>;tag=wddxn Call-ID: bdrmoffsihrozyj(a)192.168.1.58 CSeq: 636 SUBSCRIBE Contact: <sip:angel@192.168.1.58> Accept: application/pidf+xml Event: presence Expires: 30 User-Agent: Twinkle/1.1alpha2 Content-Length: 0 # U 2007/09/10 17:54:08.296369 85.92.0.210:5060 -> 222.21.235.18:5060 SIP/2.0 202 OK Via: SIP/2.0/UDP 192.168.1.58;rport=5060;branch=z9hG4bKcsmbires;received=222.21.235.18 To: <sip:ibc@sip.domain.net>;tag=10.14184.1189439648.1 From: "Angel" <sip:angel@sip.domain.net>;tag=wddxn Call-ID: bdrmoffsihrozyj(a)192.168.1.58 CSeq: 636 SUBSCRIBE Expires: 30 Contact: <sip:85.92.0.210> Server: OpenSER (1.2.2-notls (i386/linux)) Content-Length: 0 # U 2007/09/10 17:54:08.297746 85.92.0.210:5060 -> 222.21.235.18:5060 NOTIFY sip:angel@222.21.235.18:5060 SIP/2.0 Via: SIP/2.0/UDP 85.92.0.210;branch=z9hG4bKfaad.3f308931.0 To: sip:angel@sip.domain.net;tag=wddxn From: sip:ibc@sip.domain.net;tag=10.14184.1189439648.1 CSeq: 2 NOTIFY Call-ID: bdrmoffsihrozyj(a)192.168.1.58 Content-Length: 342 User-Agent: OpenSER (1.2.2-notls (i386/linux)) Max-Forwards: 70 Event: presence Contact: <sip:85.92.0.210> Subscription-State: active;expires=30 Content-Type: application/pidf+xml ---------------------------------------------------------------------------------------------------------- And after 60 minutes (presence refresh in X-Lite) the following SUBSCRIBE from X-Lite is this sent.

So, what to do??? I've a in-dialog message without "Route" header, so it's not routed by "loose_route()". I've tryied with this: if (loose_route() || has_totag()) { but it generates a loop. Does OpenSer store the SUBSCRIBE dialog info for 60 minutes? could it recognize this establishd dialog? or should I route this in-dialog message as NOT in-dialog? Thanks for any explanation. -- Iñaki Baz Castillo ibc(a)in.ilimit.es
