Welcome to our most popular resource, the World PSTN Tone Database, dedicated to the A-Z of international call progress tones. From here you can research tones, get tone plans and, if signed in, audition the tones on-line.

Help us improve! If you have new information on Disconnect tones or official versions of national tone plans, we'd like to hear from you. A big thank you goes to all contributers, with special mention to Tom Keating's VoIP & Gadgets Blog. Keep'em coming!
