Hi I don?t think there is any tone detection algorithms in PJSUA, If you want to detect a single tone I would recommend G?rtzels algoritm, you can start with http://en.wikipedia.org/wiki/Goertzel_algorithm BR/Olle _____ From: pjsip-bounces@xxxxxxxxxxxxxxx [mailto:pjsip-bounces at lists.pjsip.org] On Behalf Of Jose Suarez Sent: den 10 augusti 2009 18:19 To: pjsip list Subject: Tone detection Hi All, I'd like to know how to detect a tone using PJSUA. I'm developing a dialer and when it makes a call and play a message I want to detect during the playing of the message a voice mail tone, that tone has the following specification: Frequency: 875 Desviation: 5 It's a Single Tone. Do you know how Can I do to create this tone and to detect it? Thanks in advance, Jose -------------- next part -------------- An HTML attachment was scrubbed...
