Working to replace a cisco CM (v9.4) system to FreePBX (v14.0.1.36 / Asterisk 15.1.5).

Have several issues:

  • Current trunks are MGCP that are part of a cisco 2921 gateway. Looking for Asterisk module “chan_mgcp.so” to load and show as part of “Trunks” (Create new trunk). We are also looking to change the MGCP T1 trunk to SIP (vendor dependent).

  • Access to older intercom system that runs off an “analog” card in the cisco 2921 gateway. Found a route pattern “5.#00” that routes to “AALN/S0/SU2/0@CGHSNC_Voice_GW.cghs.crusaders”.

  • Tech note: on cisco IP Phones (Model 79XX), the “Display Name” when creating extensions is only 11 characters. The extension number is what cisco CM puts here, and a “SpeedDial” button is “labeled” for the actual user display name. Also, the “Secret” 32-charachter sequence is limited to 31-charachters.

Any help here is worth while to move this project along.
