Zoom Phone is the cloud PBX / UCaaS voice product of Zoom Communications, headquartered in San Jose, California, and sold worldwide from its United States home market. It replaces on-premise telephony with a cloud calling service — extensions, auto receptionists, IVR, call queues, shared line groups, voicemail, call recording, fax, emergency (E911) addressing, and SMS/MMS — delivered either on Zoom-provided PSTN service, on a customer's own carrier through BYOC and Cloud Peering (Provider Exchange), or resold through carrier partners. In the telecom value chain Zoom Phone sits above the network as a UCaaS application layer that buys wholesale connectivity and number inventory from carriers rather than operating a mobile network, and its API posture reflects the software half of that split rather than the carrier half: the Zoom Phone API is fully self-serve, published as downloadable OpenAPI 3.0 with 391 documented operations across 46 resource groups, a 71-event webhook catalog, a separate Number Management API covering number allocation, BYOC numbers, ported number orders, SIP trunks and 10DLC SMS campaigns, OAuth 2.0 with fine-grained phone:* scopes, a public Postman workspace, and an official Node/TypeScript SDK. It is not a mobile network operator, is not a GSMA Open Gateway signatory, and exposes no CAMARA network APIs — no CAMARA reference was found anywhere in its developer surface.
