Kevin,

How exactly and to what are you hooking this up to?  I've seen the above 
error when trying to hookup a Tellabs to our TE110P and didn't have the 
signaling correct.

-->span=1,0,0,esf,b8zs

Also, this line says to get your timing from the Asterisk machine, and 
not the provider (If there is one)
