I'm having a problem hooking up 3CX version 14 to our Asterisk platform. Version 5 works as well as version 6 but I can't seem to get version 14 to work with a normal SIP account with my provider. Thoughts? I get an error that it could not be registered and sometimes I get a gateway not found or something like that but all the time it's complaining about not being able to connect to a 3CX phone system. Thanks ahead of time!
