[Freeswitch-users] secondary outbound gateway - how to prefix?

[jungle boogie]

Hi All,

I would like to have a secondary gateway added to freeswitch. To have it 
used for outbound calling, I need to prefix the dialstring with 
something like a 9 followed by the 10 digit number.

I think that's what this page is explaining:
https://freeswitch.org/confluence/display/FREESWITCH/Configuring+FreeSWITCH

<condition field="destination_number" expression="^9(1\d{10})$">

Will that use the gateway if the telephone number is prefixed with a 9?

Thanks!
