Number Not Exist

[Guest Guest]

I use Intel Dialogic and VoiceGuide. I found out that it is hard to detect "no such number" signal. Someone knows what the frequency, period on and period off data for the "no such number " signal. Are there any standards for US telephone signals such as dial tone, ring back, busy, fast busy and "no such number" signals.

 

Thanks

Best to ask your phone company to see what tones they would play (if any) when a non-existing number is dialed.
