Hello everyone and nice that I found this forum, because I’ve been grappling with a problem for some time.
Background
Several locations should be accessible via VoiP by phone. Since we had a previously unused root server up our sleeve,
we decided to install Asterisk 16 on this FreePBX 15. The server is located in a data center and has
via a public fixed IP address.
The installation worked and the dashboard no longer shows any errors after the basic setup has been completed.
Problem
However, no phones can be registered on the server. Regardless of the Sip driver, the clients always return a Timed Out.
This applies to both softphones and hardware.
Since the whole thing now takes days, I hope that someone can give me a tip here, because the server itself seems to be working properly.
Many thanks in advance for any help.
PS: Almost forgotten - an appropriate installation in a local network worked perfectly.
There are two classes of SIP phones - Local network and remote. You say “No” phones are working, and then you say your internal phones are working fine. Which is it?
If only your external phones are not working, it is almost certainly a routing/firewall problem. Since your server is on a public IP, turn on the Adaptive Firewall for your SIP services and see if that helps.
Thank you for the answers. The mistake cleared up an hour ago. My provider runs its own firewall, but I only got access to its settings after requesting it. Only the standard ports such as 80 etc. were released in this.
