[asterisk-users] trouble with sip connection and registration

[James Sharp]

You're not going to get a telnet connection on port 5060, since that's tcp and sip uses UDP. 

Use tcpdump/wireshark on your office pbx to see if the packets are getting to you. If not, then there's something wrong inbetween. 

A firewall misconfig, perhaps. Or the unthinkable:  your home ISP has started filtering 5060.
