My Name is Lisa.
I am a project manager for IT company in NY.
We are currently in Ghana on a mission and working for Ministry of Education.
I am looking to get this information:
Disconnect Tone frequency and pattern
Something looks like that:
480hz tone and 620hz tone play sequence, with 0.25 sec frequency....
Landline system has more than 30 different tones, and we need to know what pattern using of "Disconnect status" in Ghana.
Please advise and support us.
Many Thanks, Lisa
