Hi, all I used sipp to test to forward an un-implemented SIP method, but I got 501 Not Implemented. Can freeswitch be a SIP proxy server? SIP/2.0 501 Not Implemented Via: SIP/2.0/UDP 10.10.59.161:5061 From: <sip:1000@10.10.59.69:5060> To: <sip:1001@10.10.59.69:5060>;tag=gBpay50SD2SUD Call-ID: 10-27119@10.10.59.161 CSeq: 3 TESTA User-Agent: FreeSWITCH-mod_sofia/1.0.4-exported Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, PRACK, MESSAGE, SUBSCRIBE, NOTIFY, REFER, UPDATE, REGISTER, INFO, PUBLISH Supported: timer, precondition, path, replaces Content-Length: 0 It looks like freeswitch always processes SIP messages. -- Sincerely regards, Ryanny Oct. 13
