The service provides cloud-hosted telephony functions such as voice over IP (VoIP). Its functions include a switch that monitors customer phone numbers for incoming calls and initiates calls when directed by customer applications. It also can execute predefined actions in response to calls and trigger events based on phone traffic.
API methods support call answer, dial, and hang-up along with multiple actions in response to events generated by phone traffic. Actions include recording calls and playback, redirecting to another number, and joining multiple callers for a conference call. The API also generates logs of call traffic and system activities.
