I really could use some help on this one, this is one of the last major issues before I switch to FS. I have expire-seconds set at 600, this works for several hours. Then, for no apparent reason it changes to 60 (see trace). Most calls are missed due to this issue. Why would FS change it and how can I keep it at 600? BTW retry is at 30. I spent lot's of time with traces/investigating and the ITSP watched it and says they are not changing anything. Thanks! Mario PS If it's them how do I prove it? send 865 bytes to udp/[111.222.1.36]:5060 at 15:07:22.220308: ------------------------------------------------------------------------ REGISTER sip:sip.itsp1.com SIP/2.0 Via: SIP/2.0/UDP 100.101.102.103:5080;rport;branch=hideBcm183mmt2UD Max-Forwards: 70 From: <sip:uuid1@sip.itsp1.com;transport=udp>;tag=hide37BeUD To: <sip:uuid1@sip.itsp1.com;transport=udp> Call-ID: hide-a069-49d0-b342-hide34d28 CSeq: 2914438 REGISTER Contact: <sip:gw+uuid1@100.101.102.103:5080;transport=udp;gw=uuid1> Expires: 60 User-Agent: FreeSWITCH-mod_sofia/1.0.head-git-f499c0c 2010-10-07 10-27-31 -0500 Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, UPDATE, INFO, REGISTER, REFER, NOTIFY Supported: timer, precondition, path, replaces Proxy-Authorization: Digest username="uuid1", realm="xxxtel.com", nonce="hide0000123270bed298a5fee464c4bb367750hide", algorithm=MD5, uri="sip:sip.itsp1.com", response="70000a710c1b7a363899922e6hide" Content-Length: 0 ------------------------------------------------------------------------ recv 567 bytes from udp/[111.222.1.36]:5060 at 15:07:22.321019: ------------------------------------------------------------------------ SIP/2.0 407 Proxy Authentication Required Via: SIP/2.0/UDP 100.101.102.103:5080;rport=5080;branch=hideBcm183mmt2UD;received=111.222.333.127 From: <sip:uuid1@sip.itsp1.com;transport=udp>;tag=hide37BeUD To: <sip:uuid1@sip.itsp1.com;transport=udp>;tag=9214944d68c027e4c99a14a397962871.4d99 Call-ID: hide-a069-49d0-b342-hide34d28 CSeq: 2914438 REGISTER Proxy-Authenticate: Digest realm="xxxtel.com", nonce="4caf33ab99012dadc6e7c84040e1b4ff8841a343edc5b0c3", stale=true Server: OpenSIPS (1.6.3-notls (i386/freebsd)) Content-Length: 0 ------------------------------------------------------------------------ send 865 bytes to udp/[111.222.1.36]:5060 at 15:07:22.321391: ------------------------------------------------------------------------ REGISTER sip:sip.itsp1.com SIP/2.0 Via: SIP/2.0/UDP 100.101.102.103:5080;rport;branch=z9hG4b99m5c33mrH3reS Max-Forwards: 70 From: <sip:uuid1@sip.itsp1.com;transport=udp>;tag=hide37BeUD To: <sip:uuid1@sip.itsp1.com;transport=udp> Call-ID: hide-a069-49d0-b342-hide34d28 CSeq: 2914439 REGISTER Contact: <sip:gw+uuid1@100.101.102.103:5080;transport=udp;gw=uuid1> Expires: 60 User-Agent: FreeSWITCH-mod_sofia/1.0.head-git-f499c0c 2010-10-07 10-27-31 -0500 Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, UPDATE, INFO, REGISTER, REFER, NOTIFY Supported: timer, precondition, path, replaces Proxy-Authorization: Digest username="uuid1", realm="xxxtel.com", nonce="4caf33ab00012dadc6e7c89940e1b4ff9941a343edc5b0c3", algorithm=MD5, uri="sip:sip.itsp1.com", response="b8597203297d6db518b9996f55d3dc36" Content-Length: 0 ------------------------------------------------------------------------ recv 503 bytes from udp/[111.222.1.36]:5060 at 15:07:22.421206: ------------------------------------------------------------------------ SIP/2.0 200 OK Via: SIP/2.0/UDP 100.101.102.103:5080;rport=5080;branch=z9hG4bKKm5c999rH3reS;received=111.222.333.127 From: <sip:uuid1@sip.itsp1.com;transport=udp>;tag=hide37BeUD To: <sip:uuid1@sip.itsp1.com;transport=udp>;tag=921495599c027e4c99a14a397962871.9262 Call-ID: hide-a069-49d0-b342-hide34d28 CSeq: 2914439 REGISTER Contact: <sip:gw+uuid1@111.222.333.127:5080;transport=udp;gw=uuid1>;expires=60 Server: OpenSIPS (1.6.3-notls (i386/freebsd)) Content-Length: 0
