I'm using:
[bus-ivr-main]
exten => s,1,Wait,1
exten => s,2,Answer
exten => s,3,DigitTimeout,5
exten => s,4,ResponseTimeout,15
exten => s,5,Background(npi-greeting)  ; "Thanks for calling press 1 for"

for both livevoip.com and teliax.com (both with iax), no problems.
If you want to listen to it, call 913-440-0000 and listen for the
number of rings before the ivr audio.

If you're getting something different (using the same sort of config
as above), it might be related to exactly where your did's originate.
(In other words, I'd have to guess that of the many area codes and CO's
that source their did's, some equipment at specific geographical locations
might not be configured exactly the same as other sources. But, that's
purely a guess knowing both companies rely heavily on level-3
infrastructure, and level-3's primary business is not that of a local
exchange carrier.)
