1. Ask your telco, they probably have them, but you may have some difficulty in finding somebody at your telco that has a clue about what you are talking about. You can find some lists doing some google searches for the numbers and hope to get lucky... but as far as I know, there is no "official" repository for these test numbers.
2. I wouldn;t use an overseas number personally... those calls are certainly getting encoded / decoded and reencoded several times, and more than likely getting compressed, all of which is going to have an impact... it *might* be better than nothing... but i would expect very poor results. 3. You are right, you can';t really just make one yourself from scratch, you need a source that has already been tuned properly to use as a reference for creating your own. -- Matt Watson On Thu, Dec 11, 2008 at 11:01 AM, Olivier <[EMAIL PROTECTED]> wrote: > Hi, > > I would like to tune rx/tx gains using dahdi-monitor for a system which > will be connected to french PSTN. > I'm not aware of any public phone number in France I could call to get a > "normalized 1004Hz signal". > > > My questions are : > 1.
