What Carrier means
A carrier is a telecommunications provider that transports voice calls or messages between phone numbers and networks.
In cloud communications, a platform may use one or more carriers for phone numbers, call termination, inbound routing, messaging, emergency services, and regulatory registration. The carrier layer affects geographic coverage, number availability, deliverability, audio routing, and which identity or compliance features are supported.
How it works
An application sends call or message instructions to a communications provider. That provider selects network routes and exchanges traffic with other carriers until it reaches the recipient’s network. In a bring-your-own-carrier setup, the customer keeps an existing provider while connecting the traffic to the agent platform.
Practical use cases
Keeping existing phone numbers while adding an AI agent
Choosing regional coverage and number inventory
Managing voice and messaging through an approved communications provider
Carrier choice is an infrastructure decision, not a complete conversation strategy. Teams should evaluate coverage, reliability, support, number control, regulatory tooling, and operational ownership together.
