Hi all, I am trying to register myself to my VOIP provider (budgetphone.nl) so I can accept inbound calls. However, using "sip debug" I get the following error: <-- SIP read from 81.23.228.150:5060: SIP/2.0 403 Relaying denied Via: SIP/2.0/UDP 192.168.0.3:5060;branch=z9hG4bK65bc02f0;rport=1048 From: "asterisk" <sip:asterisk@192.168.0.3>;tag=as67980981 To: <sip:sip.budgetphone.nl>;tag=48cd709ae35c71b0e4d33846252f55ea.b365 Call-ID: 709ffae32f15f8f26cb0a5243acf38af@192.168.0.3 CSeq: 102 OPTIONS Server: OpenSer (1.0.2-tls (i386/linux)) Content-Length: 0 I am behind a NAT device which forwards port 5060 to my asterisk server. Outgoing calls do work OK. This is what I have in my sip.conf: register => 3172xxxxxx:password@budgetphone.nl When I do "sip show registry" I do not see anything registered. Does someone know what "SIP/2.0 403 Relaying denied" means? Thanks, Rene
