I have a GPO 746 working beautifully on my home machine, with one of the cheap 
TDM410P clones you can buy from eBay  (it's hardly a production environment).  
Your problem most likely is indeed the dial mechanism  (you could prove it by 
seeing how your card behaves with a push-button, pulse-dialling phone).

These dials are built to industrial standards.  They respond well to field-
stripping and re-lubrication, and there are guides on the Internet explaining 
how to do this  (including the old GPO documentation).

My own solution to the slow dialling issue was just to put some entries with 
short extension numbers in the relevant context of my extensions.conf linked 
to my most frequently-called destinations; so, for example, I can call my 
parents by dialling their old 4-digit number from back in the clicky-clicky 
exchange days.

You can; but personally, I'd just use a CGI script to generate a call file.  
Tthe script does its thing, and my phone rings; then when I answer it, the 
other person's phone starts ringing and I hear ringing-out tones.

Kontact  (and probably other PIM software)  can even run a command when you 
click onto a phone number, and embed the clicked-on number into the command; 
so I used this facility to do a wget on my make_call.cgi script.
