Zapata dialplan timing

[David Cook]

First time I've played with a zapata FXS device :-) (Happens to be a 
Sangoma A200D)

I don't see anything that sets dialplan timing so I can immediately dial 
after three-digit extensions as long as they begin with "5"; Anything 
else, but 1/0, wait for 10 digits, 1/0, wait for 11+ digits, etc.

Any ideas?
