Ring fencing extensions to use different SIP trunks

[3d3dman]

What is the best way to ring fence extensions to use different SIP trunks for example extension 200 and 201 use sip trunk 1 only and extensions 202 and 203 use sip trunk 2 only?

I don't want to use prefixes.

Any help would be great.

So create two routes for the same dialplan with different gateways.

Then for each of those routes, add a condition at the beginning that matches the extensions you want.

The first condition will be something along the lines of sip_from_user ^200$ || ^201$

You can also use toll allow to limit which extension uses which route
