Hi all, I know that this topic was discussed before, but my case is diferent. The name of the network in my work is intranet, and I'm testing two computers, the first one's name is parati with ip 10.0.161.52 runing SER with the 'Hello World' config, and the other one is saopaulo 10.0.161.59 runing Kphone. I've tryed this configuration for kphone: Name: Fabio User Part of the SIP URL: fabioldr Host Part of the SIP URL: parati.intranet Auto Register: yes Wen I try to registrar with SER : fabioldr@saopaulo:~$ kphone Found 2 interfaces. SipClient: Listening UDP on port: 5060 SipClient: Our address: 10.0.161.59 SipRegister: Auth is '(null)' SipRegister: Proxy Auth is '(null)' SipClient: Sending: 12:04:16.526 -------------------------------- REGISTER sip:parati.intranet SIP/2.0 Via: SIP/2.0/UDP 10.0.161.59;branch=z9hG4bK5DD0E9F7 CSeq: 7190 REGISTER To: "Fabio Luiz Doreto Rodrigues" <sip:fabioldr@parati.intranet> Expires: 900 From: "Fabio Luiz Doreto Rodrigues" <sip:fabioldr@parati.intranet> Call-ID: 778680124(a)10.0.161.59 Content-Length: 0 User-Agent: kphone/4.0.5 Event: registration Allow-Events: presence Contact: "Fabio Luiz Doreto Rodrigues" <sip:fabioldr@10.0.161.59;transport=udp>;methods="INVITE, MESSAGE, INFO, SUBSCRIBE, OPTIONS, BYE, CANCEL, NOTIFY, ACK, REFER" res_search: NO result ! res_search: NO result !
