Jared,

thanks for your reply - Our setup isn't complicated at all - just a PRI 
coming into an asterisk box. Maybe you could answer another question for 
me - what disadvantages does a PRI have from a channelized T1? or vice 
versa.

is the TE205 the double port version of the TE120P?


Also, what's required as far as echo cancellation goes? Is that built 
into these cards or do you have to move up to a TE207P?

What is the difference between a TE205 and a TE210?


Sorry about all the qeustions - the info on digiums web site doesn't 
really make this clear.
