Kris, thanks for the thoughful & helpful response! This makes sense in the same way that a dialplan on a SIP phone would behave.

But... If I remove the 3-digit number (224) from the asterisk dialplan, I have no problem dialing 2246 successfully. If the Ascom were just seeing a 3-digit dialplan match for 224, would the fourth digit still be transmitted along the PRI? This is the basis of the puzzle, it's as if asterisk is feeding back some info about whether a complete number has been passed along.

The originating PRI system passes the entire dialed number in the d-channel
setup frame, thus the concept of a wait time for additional digits is
meaningless. Progressive digit gathering implies that the signalling is
occuring 'in-band' as would be the case with DTMF signalling on analog
lines.

You need to look in the Ascom and find the configuration table that lays out
the dialplan for the network. The PBX itself will use that information to
determine that for example, if a number begins with '4' then it is
'complete' after a total of 3 digits (eg. 411) or if it begins with 1, then
it's complete after 10 digits (1XXXNNNXXXX). After the number is considered
'complete' it will build the setup frame and transmit it to the terminating
system.

Watch the output of 'pri debug span 1' when the originating system is
dialing different numbers to see this in action.

Hope that helps.

A call inbound from the PRI requesting 2246 is always cut off at the first

match, instantly, when people are dialing in from conventional extensions.
