SOLVED: Cannot Dial 999 from Free PBX 17

Help for FreePBX
1

Hi All,

I’m encountering an issue where emergency calls (specifically to 999 in the UK) are failing when dialled from a secondary PBX. This system routes calls through a trunk to our main PBX, which runs A2Billing. While the main PBX can successfully place emergency calls, attempts from the secondary PBX result in an “All circuits busy now” message.

Notably, standard outbound calls from the secondary PBX via the same trunk work without issue.
Has anyone experienced something similar or have insights into what might be causing this?

Any guidance would be greatly appreciated.

Best regards,

HSL

If you can you post the diall patterns you have on your outbound routes for both PBX’s that would be helpful to anyone trying to help.

The first image is the main PBX that has no issues calling 999. The second image is the PBX that cannot make calls to 999.

Thank you

You’ll need to isolate the full log lines for the call on each system. Start with the first, and see if the call it attempted to thru the peer trunk. If it is, then do the same on the second system and see at which point the call fails.

Thank you so much for replying, all very helpful.

Please find the call log in the Pastebin link below

I have a feeling that the PBX is not treating the emergency call as an external call and is instead treating it as an extension.

Hi All,

Just managed to sort this.

It was to do with the custom context I was using on the trunk on the main PBX. Once I selected the same context that the main PBX was using I was able to make an emergency call with no issues.

Thanks again!!
