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...
