(See the attached drawing for my VCF Midwest display) 

I've done similar BBS setups for VCF Midwest and VCF Southeast displays
in the past. I've used surplus analog PBXs post one year ago - primarily
a Nortel MICS which I still have and can donate (I'll be at East in
spring). That sort of thing gets dumped cheap on eBay these days. That
allows connections up to 33.3K POTS-to-POTS. Multiple 16-port analog
modules can be connected to the central box via fiber. 

For VCF Midwest this year, I switched to a Adtran Atlas 890 with a mix
of TI/PRI/BRI/FXS ports with 48 internal 300 baud to 56K (v.90) internal
modems. I combined it with a terminal server so that 80 distributed
analog lines can dial each other or a 10 line 'show' BBS that can also
take connections over telnet or the terminal server. As you can see,
anyone with a cell phone can connect to the local WiFi hotspot, telnet
to the terminal server, and get an AT prompt to dial within the network.
There were a few problems revealed in Chicago I need to stream-line, but
the setup worked well. I suppose you could also telnet in remotely to
the site (termserver) and get one of the internal digital modems which
you could also use to dial.
