I would like to know if "Route List" Broadworks AS service allows provisioning extensions in addition to DN and ranges or prefix.
As we can get from documentation (r23):
Cisco BroadWorks allows an operator to bring a new site online simply by provisioning a range of directory numbers (DNs) or number prefixes for the site. This capability provides connectivity for both outbound and inbound SIP trunking calls. To support the capability, Cisco BroadWorks offers a user-licensable service called Route List and resources called enterprise trunk number range and an enterprise trunk number prefix. Route List is used to associate a DN range (enterprise trunk number range) or prefix (enterprise trunk number prefix) with an end-customer site. Enterprise trunk number ranges and enterprise trunk number prefixes play similar role, but the prefixes allow end users to have variablelength phone numbers. After provisioning is completed, the new site is able to make outbound calls and receive inbound calls using the numbers contained in the enterprise trunk number range or matching one of the assigned enterprise trunk number prefixes. The system processes such calls using the service profile of the Route List user.
The goal is to match PBX hosted users (not provisioned) and to apply originating services.
