And they also have OK rotary dial support, which was what drove me to
 try 
one out.  The VT1005 works fine with rotary dials (of all vintages)
 that 
are in decent adjustment, but there are some dials that appear to be OK
 and 
work well on the step switch and the PSTN and the Mitel SmarT-1, but
 simply 
do not work with the VT1005.  Probably the make/break ratio is a smidge
 out 
on those dials.  I've also had dials that wouldn't work with the VT1005
 one 
day, and then be OK the next.  Those are probably dials on the edge of 
whatever the VT1005 accepts and varies with environmental 
conditions.  Whatever, the VT1005 is not 100% with rotary dials.  I
 believe 
it was John J. who had a rotary phone that refused to work with the
 VT1005, 
sent the dial to be adjusted by dial expert Steve Hilsz, and the phone
 then 
worked for a short time with the VT1005 and then didn't again.

In short, for good rotary dial support (important for the collectors
 among 
us) it looks like one needs either a SmarT-1 kludge with a tone-only
 ATA, 
or a channel bank, each solution having its own advantages and
 disadvantages.

Doug.
