SIP - Trunk
- Trunk to Provider
- Trunk to PBX
Number Mapping
- In this example we have the trunk number 97517390 and the subscribers numbers will be 97517390X.
Route Settings
- Since the Provider doesn't support Overlap sending we need to use "force enblock" option in the routes. We recommend the use of "Interworking QSIG/SIP" option in the routes.
