[asterisk-users] AT&T PRI Install - What is outpulsed?

[Dave Fullerton]

Hey All,

AT&T is installing a PRI in a couple weeks and while I've been doing 
homework on PRI's for the last few weeks there's something I'm still 
confused about. After being asked how many digits I wanted them to send 
us (10) was how many digits will you outpulse to us, 4, 7 or 10? I asked 
her what that meant and all I got was the question repeated. Do any of 
you have any idea what she was referring to? Is this ANI? Outgoing 
Caller ID? Something else?

While I've done many POTS line setups, this is my first PRI install, so 
I'd also welcome any "make sure you do this", "read this first" or "AT&T 
always messes this up so..." tips.

Thanks

-Dave
