I've recently installed a second Asterisk server, this time from AsteriskNOW-1.7.0-i386, specifically because I want SIP via TCP. (This is a test system ONLY.) I thought it included Asterisk version 1.6, and I thought that Asterisk version 1.6 supported SIP over TCP.
How do I find which version of Asterisk it's running? I can see the version of all the FreePBX modules via the GUI, of course, but I can't see how to find the Asterisk version. All I have at the command line is a Linux prompt. How can I get to issue the command "core show version", for example?
Although UDP port 5060 is open and I have a couple of extensions configured and working via UDP, I can see that TCP port 5060 is NOT open as I would expect.
If there is a more appropriate distribution of Asterisk + FreePBX for my requirements, I'm happy to install it instead.
