Unable to Register Dinstar PRI SIP Trunk on Free PBX version 16. Asterisk version 18.0 After Upgrade

[Mrihan (Malik Rihan)]

Hi,

My name is Malik Rihan, and I recently upgraded my FreePBX from version 11.13.0 to 18.16.0. On the old version, I had a Dinstar PRI line configured, which worked smoothly without any issues. However, after the upgrade, the SIP trunk configuration is not getting established, and the status shows as fault.

Here’s what I have already tried:

1. Checked and updated the Trunk Settings to simple, default settings for easy compatibility.
2. Verified the network and connectivity between the FreePBX server and the Dinstar PRI gateway. (Connectivity is happening)
3. Tested with basic configurations, but the SIP registration fails, and no calls are going through.
4. Firewall and everything disabled for test purpose still same issue
   I would appreciate any insights or suggestions to resolve this issue. Please let me know if additional logs or configurations are needed.
   Thank you for helping me in this in advance!

What, if anything, appears in the Asterisk log (/var/log/asterisk/full) when the Dinstar attempts to register? If nothing, run sngrep and report what appears there. If also nothing, check that the local IP address of the PBX matches the address to which the Dinstar is registering.
