MITvoip is the authoritative directory for all phone numbers; You log into MITvoip to view/assign the subsystem(s) handling each extension, including physical hardware assignments, Zoom Phone assignments, and so forth. If you wanted to assign another application - such as another PBX - it would likely be done through MITvoip (but we don't have anything like this set up).

It is probably possible to direct extensions to an application other than Zoom Phone using voip.mit.edu, should we ever desire to do so.Each branch extension is a phone number within MITvoip/Zoom Phone. MITvoip). This means that the CRE Main Call Tree (Business Hours) is a branch, the CRE Main Call Tree (Off-Hours) is a branch, the CRE Reception Call Group is a branch/number, and so on...
