We have an internal SIP server using Asterisk in our office, all of our staff use these phones without issue (inside the office).
What we would like to do is have it so people with external SIP capable devices can also use your SIP server.
I have setup the SIP features in our Astaro, with the SIP server been our SIP servers public facing IP address.
I have then made the allowed SIP networks, ANY.
When I attempt to use a SIP device that is out on the internet I can see in the Asterisk logs that it registers but then straight away disconnects, its like it has only incoming communication with the SIP server.
Any suggestions on how this should be setup?
Thanks
