Hello, I have a problem with our server at work. None of our SIP phones are able to register. If I look at the CLI I can't see the phones attempting to regsiter. Also if I do a sip show peers I get no such command. There isn't any SIP commands available from the Asterisk CLI. Not sure if this is something basic, I am not that experienced with Asterisk. I tried to look through some logs but couldn't see anything that really helped. SIP is not being restricted on our Local LAN. This problem seemed to happen all of a sudden. Any help would be much appreciated. Cheers, Ron.
