I've recently setup Elastix, and setup extensions, etc - however when it comes to having Cisco IP phones, and a SIP Soft phone connecting to the Elastix box, it doesn't work. I was pulling my hair out trying to figure out what it was, but ended up checking if the port was actually open by telneting to it, and checking if the port was open on the server, and found out port 5060 was not open on the server:
[root@pbx asterisk]# lsof -i:5060
[root@pbx asterisk]# netstat -napt | grep asterisk
tcp 0 0 0.0.0.0:5038 0.0.0.0:* LISTEN 8704/asterisk
tcp 0 0 127.0.0.1:5038 127.0.0.1:56084 ESTABLISHED 8704/asterisk
[root@pbx asterisk]# netstat -napt | grep 5060
I've restarted Asterisk several times via the command line, as well as reboot the entire server, but I'm not sure how to get it to listening on port 5060 so our Cisco 7960s can connect to it.
Does anyone know how I can fix this?
