Hi, I have a asterisk/voip newbie and I am sorry if my quetion is banal. I used Express talk, in my LAN with Asterisk, with this configuration in Lines menu: Setting for Line: Default Line Settings Full 'friendly' Display Name: port SIP Numeber: 200 Server: 10.0.0.112 Password: mypassword In menu Network: Local SIP Port to Listen on: 5070 Local RTP ports: 8000 My sip.conf: [200] type=friend callerid=port username=200 secret=mypassword host=dinamic context=internal My extensions.conf: [internal] exten => 200,1,Dial(SIP/200,20) ..but in Asterixk log file I have: Registration from '<sip:200@10.0.0.112>' failed for '10.0.0.230 - Username/auth name mismatch and on Express Talk I have: Register attempt for sip:200@10.0.0.112 failed 404 Not found ..where: 10.0.0.112 -> asterisk ip address 10.0.0.230 --> express talk ip address ..where is my error ? thanks. Salvatore.
