Thanks Bert. It has been quite a while I have posted. Life is busy and previously it used to be only my wife's practice so used to pay lots of attention, but now she is in a group. I still take care of the group, but most of machines are VM's and have replications.
I have a mainpipe modem on a server with snappy fax and works well. Yes it is single line, and failover is MF printer with fax. I agree Mainpipe is solid and works so well.

I need to upgrade the AC from something 8.4 to whatever it is 9.? . When I started AC in 2009 or so , in 1 year it was 1GB db, now we are almost up to 4Gb and almost 28 GB in imported folder.
