It would be good to have the possibility to create a “flexible” mapping instead of assigning a DDI per user. I think we could set for example a wild card like “XXX” (last 3 digits of the incoming number) and map these to extensions, ring groups or queues. Is there a reason why it must be put fix into the PBX? These setting would make life easier. An additional “?” wildcard could be used to route any unknown DDI/DID to the operator for example.
