After many tears I finally got my two HT-503s configured with FreePBX. Now I think I have the trunks and Inbound/Outbound routes setup correctly using this:
But I’m unclear on how I get these lines provisioned on my Grandstream GXP2130 phones. I can directly dial the HT-503 extensions I’ve setup to get a dial tone and am able to dial out. But I need to get these assigned to a button so the lines can be selected and inbound calls can ring. I’m not quite sure how to do that.
Do I assign an extension number to the trunk and set that up as a speed dial? If so, how do I connect extension numbers and trunks?
I guess I’m asking a more complex question than I thought. Looking around, the answer I’ve come up with has two parts.
The first uses the Outbound Route CID. I think I can use that as an extension number and dial that from my phones. Hopefully I can specify it as a speed dial and get a dial tone.
The second is to setup a dial plan in extensions_custom.conf for inbound calls using the DID I specified for the inbound route and using the internal-phones context coming from the trunk:
This should ring all my extensions on an inbound call. I haven’t yet had a chance to test any of this. Does this sound sane? Am I going down the right path?
