So, I'm trying to use a regular door phone intercom unit with a 616.
I made the mistake of vetting my idea on a CICS so got my hopes up. The idea was to use an ata to connect a Viking e-20, have it hotline to a hunt group (broadcast) that had all the phones in it. Turns out 616 DR2 software has neither hotline or hunt groups...

I can get a DR5 cartridge easy enough, but looking at the manuals, there does appear to be the hotline capability, but not so much the hunt group.

Short of replacing it with a CICS (tempting). Any other ideas for programming this situation?
