The service provides incoming VoIP telephony functions for accepting and answering international calls. It establishes virtual telephone numbers local to callers, then forwards the calls via voice-over-IP (VoIP) to remote call centers for cost-effective responses. Users can answer calls from anywhere in the world while providing local numbers and without international calling charges.
API methods support listing countries where local numbers and services are available and areas within those countries. Methods also support account management, including call history and current balance. The API reports on all direct inward dialing (DID) numbers established for an account and its session session initiation protocol (SIP) status.
