Set Variable for Extensions

[Alexandre Aranha]

Hey guys,

I am configuring CGRates to work with FusionPBX.

I need to set up 2 variables for each extension to define the billing method per extension. Prepaid or Postpaid.

For freeswitch, is necessary to add theses variables in the extension xml file.
<variable name="callgroup" value="techsupport"/>
<variable name="cgr_reqtype" value="*prepaid"/>

How could I do that with FusionPBX?

thanks.
