Grandstream GXW4104 Outbound Dial Plan


Hi all,

We recently purchased the GXW4104 FXO and added 2 Analog lines.
Where can I find a documentation regarding the dial plan.

The goal is to be able to map which line will be used in the outbound base on the number dialed.


i have the same issue too and i need help


Hi @shadii717,

This is where you make the config

I don’t know what is your PBX is but in my case, I have to prepend the prefix followed by the port number.
Ex. 31 = Prefix configured + 1 = port number
So 311 is port 1 and 312 is port 2 and so on.
