[VoIP] Dialing Tests w/Motorola VT1005

I have been playing around with the VT1005 and the phones here and I am 
impressed!  The Motorola VT1005 does remarkably well with the range of 
vintage dial sets connected to my step switch.

I connected one of the CNET ports from the switch to Line 1 of the VT1005 
last night and have been testing and trying the step switch stations 
scattered about the premises here.  The phones range in age from a pre-1930 
WE 51AL dial candlestick with #2 dial to late WE500s with #9 dials.  I have 
had only two dialing errors, one was with a call attempt on my ComKey 416 
set, but a subsequent call placed went through w/o errors.  The other was 
with my WE 460 multiline set.  Again, got an error on one call, next call 
attempt went through OK.

What was most interesting is that I had no problems dialing from a SC 1543 
set with a really pokey dial.  I need to send it to Steve Hilsz for some 
rehab, but I got the number I dialed from that set via the VT1005 on the 
first attempt.

The rotary dial sets I have tried are:
* WE51AL 'stick w/#2 dial
* Various WE500s with #7 and #9 dials
* ComKey 416 rotary dial Master set, 1 error
* WE440EC-3 set connected to a 1A key system
* WE460-series, 1 error
* Federal 802A1 desk set (302 look-alike)
* NE Contempra
* AE80
* AE40 (3 different sets)
* SC 1543 (2 different sets, both w/sluggish dials)
* SC 1243
* WE701 Princess
* Connecticut "Toaster" phone
* CTE (North 7H6 look alike) w/AE dial
* WE830 connected to a 1A2 key system
* WE302 w/#5 dial
* Leich 105
* WE302 w/#6 dial, can't dial out.  Must be pulsing faster than 10 pps or 
m/b ratio is out of whack, will not break dial tone on the VT1005, though 
will dial OK on the step switch, and the SmarT-1/Sipura setup.
* WE5302 w/20 pps dial -- won't break dial tone on VT1005, but doesn't work 
with the SmartT-1, either

All of the phones are in "as found" condition in terms of their dials.  I 
do have a 302 with a "Steved" dial, but it is currently in pieces and not 
operational awaiting the metal case from a friend who is repainting it for 
me.  In short, the VT1005 makes a good accounting of itself with the phones 
here.  It looks like a winner for those who want to avoid the SmarT-1 
pulse-to-DTMF conversion required with other ATAs.

Cheers,

Doug.
