Caller Ring Back Tones
Caller Ring Back Tone (CRBT) is one of the many value-added services that has seen incredible adoption in recent years. This service allows customization of the ring back tone. When a call is placed, the caller hears an audible alert through the phone. The alert indicating that a call is successfully going through is called the ring back tone. Other tones that may also be heard at this stage of a call are an engaged or busy signal or an operator intercept tone.
CRBT is a service by which the person who is receiving the call can customize the ring back tone, based on the phone number of the person who is placing the call.
There are several approaches to delivering this service. The Sangoma method is cost-effective, relying on quality Sangoma equipment and open source software.Download Whitepaper
