Step1. Create an invalid SIP trunk
Create an invalid SIP trunk in “PBXVoIP trunkService Provider”. The IP
address can be an invalid one, like 1.1.1.1.
Figure 4-2
Save it and apply the changes. The status of this trunk is unreachable of course.
That’s what we want.
Step2. Create an oubount route for all extensions and this trunk to
route international calls.
ClicK “PBXOutbound Call ControlOutbound Route”, create a new one:
Name: NoInternational
Dial pattern: 00. <Don’t miss that dot here>
Strip: 0
Choose all extensions and that special trunk (Invalid_international) to the right
side.
