[asterisk-users] oddity with TDM400P / Asterisk setup

[Ted Wallingford]

Hey, in case anybody has this problem.  I went out to the location of  
the Asterisk box and found two problems. The default gateway, a  
sonicwall, was sharing an ip address with a wifi point (doh) and a  
patch cable plugged into his switch on both ends (doh again).
