[Asterisk-Dev] Performance bottleneck in voicemail2 on nfsed huge mailboxes

[Levent Guendogdu]

... another "workaround" just popped into my mind, which would be
simpler to implement IMHO:

after playing the beep, record the voicemail audio to a (some) tmp
file(s), like 

/tmp/<currentsystemtime>.gsm

After hangup, look for the next msg num and save the meta file and
voicemail.

Sounds good to me for a first step, if no one objects, I'll patch this.

Levon.
