I just tested this in my PM3 which has two trunk-side CT1's (ESF/B8ZS)
running ComOS 3.5.1b20.

I went through and turned off all unused modems, then I called into the
PM3. The call went through, I got a silence, and then about 10 seconds
later it hung up on me and I got a dial tone again. sigh.

As others have already responded, they say it should return a busy signal.
It doesn't for me.. what are the requirements? That the hunt group roll
over to another PM3?

It should return a busy signal anyway.. this kinda of behavior is starting
to defeat the fail-safe digital modem concepts.
