I need to have a computer automatically call my office and maintain the telephone connection for at least 2 minutes. The reason for this, is I've contracted with a squirrelly VOIP provider that I can expect will have downtime about 1% of the time (and not bother to warn me). Is there software that can operate in either of the following configurations:

  • laptop with modem connection to plain old telephone network (which I could connect to home telephone line;
  • App for an Android phone that would automatically dial at the same scheduled time each day?

This actually ends up saving me about 5 minutes each day that me, or member of my staff, would spend calling in from a cell phone, and adding it to a log.

  • It would be useful to know what operating system(s) you're talking about, because I doubt there's any solution that applies to all of them. – John Gardeniers Dec 12 '10 at 22:14

You could try Dial Engine Pro using a script and running it from a scheduled task: http://www.phonedialerpro.com/#Engine


Warvox wasn't designed for this, but I think it could meet your requirements. It's a wardialing tool, but instead of using a basic pots modem, it uses an IAX trunk.

It has logging and reporting facilities, which could help you to graph downtimes.

iWar is more basic, but maybe more scriptable. MySQL logging, modem & voip support.


You're doing it the hard way for sure. If you have Cisco equipment, you can use IP SLA to generate voice streams and measure jitter, latency, MOS score, etc.

  • and Juniper has an equivalent called RPM that works fairly well, thought its not as in depth, IMHO. – SpacemanSpiff May 15 '12 at 13:16
