CPT-Master

Incorporating the World PSTN Tone Database, CPT-Master provides convenient generation of Call Progress Tones for telephony developers and telco engineers. Simply load a preset setting (about 1,700 records for more than 190 countries), or specify your own custom tone by entering frequency and cadence strings. The trial version is fully usable and does not expire, but its built-in database is restricted to just a few countries.

Version 2 comes with an updated and expanded tone database and with an improved tone generation engine. Now displays templates for Sipura/Linksys and Zaptel/Trixbox/Asterisk configuration strings.
