[Asterisk-Users] Asterisk Hardware Recommendation

[Daniel Salama]

Thank you again. I will definitely do that. By "cheaper" asterisk 
servers, do you mean single-CPU machines that can handle Quad T1s and 
still do the call monitoring?

BTW, I tried the monitoring without the 'm' option and mounted the 
audio directory via NFS. Big NO NO for everyone. Just do what Matt 
says: copy the -in and -out to archive server separately several times 
a day :) - don't record to NFS mounted drive.

Thanks,
Daniel
