Outbound Route Configuration
In order to make outbound calls, your system needs to know what it’s allowed to route and where the calls are to be routed. We’ll set these up to guard against people making unauthorised calls on your system.
If you do not wish to make international calls, leave out the 0011 route pattern.
To save yourself from grief later down the track, configure a prefix to route all external calls. In Australia, we use 0 as a standard. This will ensure internal numbers will never overlap external destinations.
1. Within the Connectivity menu, select Outbound Routes and Add Outbound Route
2. Label your route, and select the SIP trunk previously configured.
