Is this the best way to set this up? Is there really no way to generate an internal only "virtual extension" that we can point to the SPA122? Or to just block external access to the DID?
Follow up question, if this is indeed the correct path, will the approved users be able to dial the paging line using the direct extension? Or only via the full number?
Sorry if this is a question that has already been asked, I promise I searched the community before posting.
