The above says you do not have an entry like:
[from-pstn]
exten => 632254 dowhatever

The "s" exten does _not_ match everything. You're incoming call is to a
specific exten and you need to have a specific entry to handle it. That
might include a Goto for some other context, etc.

Same exact problem.

I typically use something like this for incoming calls:
[teliax-incoming]
include => bus-ivr-main
exten => 3032223333,1,Goto(bus-ivr-main|s|1)

[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"
