Calling Party Number for Extensions
By default the SL1100/SV8100 will present the Trunk DDI which is the User ID setup previously for all
outbound calls. If you wish for some/all extensions to display different User DDI(s) we recommend that
you set a DDI for each extension on this page.
The below image shows our example deployment where SIP Trunk User 1 is Extension 210 and User 2
Extensions 211.
