CEN’s independent PBX federation
CEN describes a federation connecting independent community telephone and PBX networks through three-digit area codes and member routing APIs, without requiring local renumbering.
- For
- Operators of independent community PBX networks
- Worth noticing
- The page distinguishes the recommended 88 dialing prefix from the official CEN number; it says the prefix is locally configured.
Field notes
The published numbering example keeps local number 315-1234 intact and adds area code 214, while a different area code distinguishes an overlapping local block. CEN says its directory selects the destination member network; that network’s Routing API resolves the local number and PBX. Integration links name PHP, PHP/Python AGI, and a FreePBX configuration generator. The page also separates API-key authentication from separately established IAX trust.
