[TriLUG] asterisk cpu requirements

[Wing D Lizard]

Jon hinted that it needs to be fast.  What is the reason for this?  I
have say two trunk lines and two extensions.  I'd like to use it for
a smart answering machine, handle maximum of two calls at a time,
and maybe a voip call.  I'm planning on using the digum hardware.

has anybody got this running on a low end cpu?

what size memory is required.  I have an old dell I'd like to use,
I think it is 400mhz p3 with 384Mb.
