configured numbers.
If you select the this option, specify "assigned numbers" by
clicking the Add button and entering the numbers. To edit or
delete a number you added, select it and click the Edit or Del
button. Enter a calling number in the field below the table in

Check this box if the SIP service provider uses SIP Record-
Route and the SIP trunk cannot make or receive calls. If it
already works, DO NOT CHECK or UNCHECK this box. [Service
provider Bandwidth.com with Edgewater Route require this
checked]
When a call comes in, the SIP trunk uses To Header or
Request URI as the DID/DNIS number
