I've been noticing lately what seems to be some distortian in the standard asterisk sound files, used for voicemail. These files are stored on the local Asterisk system. When Asterisk plays them, I can hear some cracles and pops. I'd never noticed these until recently. I did a little test. This sounds fine... exten => 1000,1,Answer exten => 1000,n,Wait,1 exten => 1000,n,Playback(digits/p-m) exten => 1000,n,Hangup while this causes some cracks and pops to be heard during the playing of the 'p-m' file. exten => 1000,1,Answer exten => 1000,n,Wait,1 exten => 1000,n,Playback(digits/7) exten => 1000,n,Playback(digits/p-m) exten => 1000,n,Hangup If I replace digits/7 with digits/8, I get the same result. But, as I said, if I just play digits/p-m, I don't hear the distortion. I haven't got a clue what could be causing this. Does anyone else? Doug

Just a thought.Thanks for the reply. I just worked out what it was. I had ulaw copies of all the sound files in the digits/ directory. For some reason, the ulaw files either had the cracks and pops in the recordings, or when asterisk played the ulaw files, it generated the cracks and pops. Doug.
