[asterisk-users] new user help required to build voice recorder with asterisk

[Steve Totaro]

It depends on what you do with them.

Years ago, 60 calls would start to crap out audio on live calls and I
learned that the hard way on a production call center.  There was the
I/O of just SLIN, then converting to MP3, then transferring to a not
too forgiving SAMBA share.  Scheduling things for a slower times and
moving the MP3 conversion to the mass storage significantly helped
while scrambling to find the permanent solution.

People could increase those numbers with RAMDisk and other tricks but
just moving it off the "Phone System" makes more sense.

Why not engineer something to scale and last without knowing that you
will have to revisit it and quite possibly at the most inopportune
time, like when you just spent a good deal of money on an advertising
spot?

Thanks,
Steve T
