Adding suffix to trunk numbers

I am using a fct module for connecting gsm to pbx. But it’s an analog line. I have connected it to my fxo gateway to connect it asterisk. The problem is waiting too much to call on gsm gateway. I need to add suffix to add # sign. For example XXXXXXXXXX+# but this is not working. I need help please. Thanks

You can do this in the config files, but I don’t think you can do it from FreePBX.

exten => _x.,1,goto(outbound-allroutes,${EXTEN}#,1)

The above line of code will put the # at the end of the number. You could probably put this in extensions_custom.conf under


You will need to modify your outbound route to that trunk in FreePBX to include the “#” in the dial pattern.
