I am working to interface a FreePBX with an old analog Dukane intercom system for a school.
- FreePBX 14 using SIPSTATION
- Grandstream HT813 to provide FXO for Dukane.
I have followed forums, wikis, and other documentation to setup the Grandstream and the additional SIP trunk in FreePBX. I am stuck with how to setup the Outbound Route for that trunk. I don’t want it to conflict with SIPSTATION, however I want to have the ability to dial a specific number from some endpoints in order to connect with the Dukane to make pages.
What should I use as a dial plan in this outbound route? Or am I mistaken with having to use an outbound route at all? I assumed I needed it since how would FreePBX know what to do with a call to the Dukane?
Yes, the original installers of this Dukane intercom system confirmed that I would need a FXO for the PBX, however they could not tell me the required settings. The ancient Comdial PBX that was originally used was destroyed years ago in a lightning storm.
Thank you for your help!
