[VoIP] Recordings / My Asterisk & Router

Sat Feb 2 09:13:35 CST 2008

I also have a Linksys 8 FXS ATA and have about half the ports populated with 
no problems so far in four weeks.

The only problem I find is the noise level from the fan!  You can hear it 20 
yards away!   Does anyone-else have this problem with the fan?
