[asterisk-users] trouble with sip connection and registration
I have a home asterisk box which connects to the office asterisk, so I can just dial extensions. This used to work just fine. I'm using 10.0-rc1 on the home box, 1.8.7.0 on the office. But it doesn't work now: [Nov 14 18:38:19] NOTICE[21563]: chan_sip.c:13161 sip_reg_timeout:-- Registration for 'sip@officePBX' timed out, trying again (Attempt #86) I first thought it was some fall out of the new upgrade to 10.0-rc1, but now I'm not sure. Even with verbose at 6 I don't see anything on the office console about the attempted registration. And on the office: lsof -i:5060 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME asterisk 2045 asterisk 15u IPv4 23030 0t0 UDP *:sip but: telnet localhost 5060 Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused iptables is set to allow 5060 udp and tcp. And I've flushed iptables, but still no luck. I can ssh into the office box from the home box. The office box is directly connected, the home nat'ed. Any help really appreciated. sean -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] trouble with sip connection and registration
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.

Telnet is TCP while SIP is usually UDP.
The 'Connection refused' just means you don't have telnetd running (a good
thing) or anything else (xinetd, honeypot, etc.) listening on that TCP
port.
iptables is set to allow 5060 udp and tcp...
127.0.0.1 is assigned to the 'lo' ('loopback') interface and probably not
filtered by your iptables rules.
If you enable SIP debugging on your home and office Asterisk servers, does
that yield any clues?
tshark and wireshark may also yield clues.

Used wireshark: I can see the REGISTER packets going out from the home router, but nothing from home:5060 shows up at the office. Bummer. Now I get to think about how to set up special ports between home and office. A great evening activity. sean -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Now I get to think about how to set up special ports between home and office. A great evening activity. I've always used a VPN to get around BS like that. A home router running dd-wrt connecting via PPTP to your server, problem solved. I'd also call your ISP and hold them accountable and ask why your traffic is being filtered. And which ISP are you using? That way we all know which ones like to play games with SIP packets. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
