[VoIP] Asterisk-SIP Trunk

Sat Dec 22 16:51:32 CST 2007

Someone, possibly Doug, has or had 3.
Others can't use 2.
All depends on the Motherboard and how they do or do not share.
Generally the X100P is a POS, and its use is discouraged.
Echo problems due to poor mismatch
I am really surprised the UK guys can use them at all. The users lists 
report more problems than successes.
