Want to setup custom outbound Dial suffix #000X on my outbound routes. Since my VOIP need the suffix in order to connect the call. I’m using FreePBX FreePBX 188.8.131.52 is this posible?
That is generally done in the trunk’s “Dialed Number Manipulation Rules” for a suffix (unusual) you might need to do something conditional in your "macro-dialout-trunk-predial-hook " context.
(you should consider updating your system, yours is no longer supported)
