[asterisk-users] ChanSpy in whisper mode - low quality audio

[ISABEL ORDAS ARNAL]

Hi all,

I succeed in injecting audio into one channel by mean of ChanSpy, but this audio cannot be listened correctly. I am using softphones for Android and iPhone and there are so many cuts so that they cannot understand what is said in the audio file. Is this because the total RTP bandwidth is too much?. Which codec and format should I use for the files played with Playback application?

Dialplan is like this:




same => n,Dial(SIP/${TRUNK}/${ARG2}${NUM},60,M(inject^${CALLERNUMBER}))



[macro-inject]

same => s,1,Originate(Local/trunk at injectWarning,app,Playback,Message-Callee)

same => n,Originate(Local/${ARG1}@injectWarning,app,Playback,Message-Caller)



[injectWarning]

exten => _+34[69]XXXXXXXX,1,Answer()

same => n, ChanSpy(SIP/${EXTEN},qw)

same => n, Hangup()



exten =>trunk,1,Answer()

same => n, ChanSpy(SIP/${TRUNK},qw)

same => n, Hangup()



Could anyone help?



Regards,

Isabel
