Long story short – I have an ancient Britsh Telecom phone attached to my Asterisk PBX via Dahdi. It works beautifully, receiving calls, and the call quality is excellent. However, dialling out is impossible, as Asterisk consistently mis-reads the number of pulses the dial sends (it could be a squiffy dial, I’m not sure). Not to mention the fact that, in today’s modern “want it now” age, waiting up to 3 seconds between digits whilst the rotary dial does its thing gets old very quickly…

As with all Dahdi connected phones, when I lift the handset, I
immediately see:

— Starting simple switch on ‘DAHDI/x-y’

Can I run a script (either in extensions.conf, or ael, or whatever) when that is detected? If so, I will create a small app which allows me to type a telephone number on my computer, I can then lift the phone & the script will go find the number I typed, and dial it for me.

Thanks in advance!

  • 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.
