I’m a new FreePBX user and have done a basic setup of FreePBX 17.0.19.16 with a publicly routable IP address. I am able to make calls between extensions, everything works smoothly out of the box. Thanks for the great experience!
Now I want to call and receive calls from accounts on other SIP servers, for example sip.linhome.org. When I try to call these accounts, e.g. sip:[email protected], the call doesn’t go through and I don’t seem to be reachable from there.
What do I need to set up to make and receive calls from SIP servers all over the world? Finally, I would like to point out that I’m not using any SIP trunks or accounts to call numbers on POTS (and I’m not interested in calling POTS, just other SIP accounts as explained above).
Any help on this would be greatly appreciated.
