Hey thanks for your answer...:)?and by wrong freq i mean inappropriate freq..(may be i am wrong,ignore the point if such :) ) Now i want to know that,yes "tonegen" plays dual tone that i know,but does it mixes frequencies based on modulation(*) or conjugation(+) ??? and surely it does only 1 of them,then how to make other alternative possible??and what is use of 'freq2' in 'tonegen'?? becoz in documentation it is stated that freq2 is optional !! Thanks in advance,Vikas Khanna. --- On Wed, 16/11/11, Nanang Izzuddin <nanang at pjsip.org> wrote: From: Nanang Izzuddin <nanang@xxxxxxxxx> Subject: Re: Tone generation by frequency modulation(f1*f2) and conjugation(f1+f2) !! ??? To: "pjsip list" <pjsip at lists.pjsip.org> Date: Wednesday, 16 November, 2011, 3:54 AM Hi Vikas, Not really sure how freq can be wrong :) FYI, the tonegen can generate dual tone (dial/ring/ringback/etc) by mixing samples of both freqs (freq modulation?).
