How to direct outgoing call to specific FXO Gateway port

[junn]

Hello,

I am using a Grandstream GXW4104 and connected 2 PSTN on port 1 and 2 and MagicJack on ports 3 and 4. Everything worked out fine but I wanted a certain dial code like "9" would use specific ports 1 and 2 and maybe "8" on ports 3 and 4 on the gateway.

Is there a way to do this on the system?

Thanks in advance for the help.

You must split the ports into separate trunk groups unless your gateway is capable of selecting a port based on a prefix. I believe that some Grandstream gateways operate that way.
