The service provides voice-over-IP (VoIP) telephony with a number of features designed to give low-cost voice communications. Applications can schedule and send mass phone calls to recipient lists and play a message recorded in a file uploaded with the request. Applications can initiate VoIP calls with buttons or other controls on a web page or initiate callback services that reconnect a local call to a remote recipient via inexpensive VoIP connections.
API methods support Voice Blast to deliver a recorded voice message to specified recipients, from one or a few to a long list. Methods also support voice call functions initiated by controls embedded in web page HTML. The SetuBilling API supports resellers in developing their own click-to-call solutions. A callback API allows a voice call to a local number to trigger a new call between the same parties, local or remote to one another, via VoIP.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
