Hi, I'm new to freeswitch and I'm trying to set up 2 polycom phones running 4.0.2 firmware to share a line. I followed the wiki pages http://wiki.freeswitch.org/wiki/Shared_Line_Appearance and However, whenever I pick up an incoming call or try to make an outgoing call on one of the shared lines, the other line doesn't detect that the line is in use and I get a massive dump of 481 and 482 errors dozens of times. I have no idea what is causing this behaviour, any help would be greatly appreciated send 854 bytes to udp/[10.10.8.81]:5060 at 02:03:54.850984: ------------------------------------------------------------------------ NOTIFY sip:1000@10.10.8.81 SIP/2.0 Via: SIP/2.0/UDP 10.10.11.1;rport;branch=z9hG4bKcHKrvF7SKSp1j Max-Forwards: 70 From: <sip:1000@10.10.11.1:5060>;tag=AWBzYjyr5AtS To: "ppcBarge2" <sip:1000@10.10.11.1>;tag=FC20B986-C3012B3F Call-ID: d753ed55-db70fc4e-bddaf407@10.10.8.81 CSeq: 4053008904 NOTIFY Contact: <sip:1000@10.10.11.1:5060;transport=udp> Call-Info: <sip:10.10.11.1>;appearance-index=*;appearance-state=idle User-Agent: FreeSWITCH-mod_sofia/1.2.3 Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE Supported: timer, precondition, path, replaces Event: call-info Allow-Events: talk, hold, conference, presence, dialog, line-seize, call-info, sla, include-session-description, presence.winfo, message-summary, refer Subscription-State: active;expires=3600 Content-Length: 0 ------------------------------------------------------------------------ recv 405 bytes from udp/[10.10.8.81]:5060 at 02:03:54.864355: ------------------------------------------------------------------------ SIP/2.0 482 Loop Detected Via: SIP/2.0/UDP 10.10.11.1;rport;branch=z9hG4bKcHKrvF7SKSp1j From: <sip:1000@10.10.11.1:5060>;tag=AWBzYjyr5AtS To: "ppcBarge2" <sip:1000@10.10.11.1>;tag=FC20B986-C3012B3F CSeq: 2147483647 NOTIFY Call-ID: d753ed55-db70fc4e-bddaf407@10.10.8.81 Event: call-info User-Agent: PolycomSoundPointIP-SPIP_550-UA/4.0.2.11307_0004f2149566 Accept-Language: en Content-Length: 0 ------------------------------------------------------------------------ Thanks, Ken
