[Asterisk-Users] Adpcm quality

[Alex Zarubin]

Please, try

exten => 99,1,Wait,1
exten => 99,2,Record,/tmp/pcmfile:pcm
exten => 99,3,Wait,1
exten => 99,4,Playback,/tmp/pcmfile
exten => 99,5,Wait,1
exten => 99,6,Record,/tmp/voxfile:vox
exten => 99,7,Wait,1
exten => 99,8,Playback,/tmp/voxfile

(put your own extension).

Pcm recording is OK, playback is OK.
Adpcm recording is noticeably worse. Adpcm playback is very bad/unusable.

Is it just us (all our servers with T400P and TE410P), or it's a common
adpcm codec problem?

Thank you.
