[asterisk-users] Garbled voicemail

[Stefan Schmidt]

Hello,

this is a know problem when you are writing the voicemails over a nfs
link. you have to start asterisk with the -t option to write voicemail
records to the local /tmp and copy it to the final destination after it
is finished.

as far as i remember the first 10 seconds are ok and then the speed up
started but with the -t option it was completly solved.

best regards

stefan
