Hi,<br><br>I would like to tune rx/tx gains using dahdi-monitor for a system which will be connected to french PSTN.<br>I'm not aware of any public phone number in France I could call to get a "normalized 1004Hz signal".<br>
<br><br>My questions are :<br>1. Does such numbers exist ? Is there a directory somewhere listing some of them ? Do you think regulations could make providing such numbers mandatory for (some) Telcos ?<br>2. Does it make to use a number aboard instead if I can't find any local ones ? I don't think so, but I prefer to check.<br>
3. I can't imagine a process allowing me to create my own (chicken and egg problem). Is it correct ?<br><br>Regards<br>
