[Freeswitch-users] Tone Stream and G729

Hi All. I am wondering if somebody can point me in the right direction. I am playing back tone_stream on my call, but noticed that if the codec is in G729, the call fails because of a codec negotiation error (I am loading the G729 mod). Does anybody know how tone_stream can work with G279? Here's the line from my dialplan (NumberOfLoops depends on how long it takes us to find the user, historical average): <load module="mod_g729"/> <action application="playback" data="tone_stream://%(2000,4000,440.0,480.0);loops=${NumberOfLoops}" /> Thanks, Alex
