try 1,1,0,esf,b8zs 

I am assuming this is the only T1 in this box.  Don't need the dynamic line 
(it's commented out anyway).

You're misunderstanding the clocking parameter:

0 = do not use this span as a clock source
1 = use this span as the primary clock source
2 = use this span as the secondary clock source
3 = use this span as the tertiary clock source
... etc.  You need a clock source.  The secondary, tertiary and so on only 
become the clock source if the primary (or secondary, and so on) is down.  

Since I think you want to use the PBX as the clock source you should be giving 
it a value of '1', as there are no other T1s in this box and the zaptel card 
needs clock to come from somewhere.  i.e. it needs SOME T1 to be a primary 
clock.
