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 tone parameters in national tone plans and, if signed in, audition the tones on-line and switch formats.

Corporate customers can subscribe to our Premium search and benefit from unrestricted searching, full cross-referencing of over 1,700 records, update notification and support.

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 our subscribers and contributors, with special mention to Tom Keating's VoIP & Gadgets Blog. Keep'em coming!
