Wash,
From zain, please call another zain line, press a digit from the calling phone, you should hear a sound/tone on the other phone. That will show whether DTMF is available in that network.

Hello Skunks,
Hi Wash,
When I was almost hitting my /etc (End of Thinking Capacity), I figured out I could try swapping the Zain line for a safaricom line, just a hunch. I did this and voila! DTMF worked. Now after much testing, I realize that DTMF works from Zain <->Safaricom, from Zain->Telkom but NOT from Zain->Zain. Could this just be a misconfiguration on Zain's systems or a security
Could be be either....IMHO
feature that they implemented and know about? Is there a reason a GSM operator would want to block DTMF on their systems?
Probably...may many reasons... :)
I am asking this because I have wasted almost 72 hours on this, only to come and realize this "anomaly" on Zain's network. I'm really pissed off with Zain. However the system I am implementing MUST work with Zain so I need some clues before I go knocking on their doors to enable DTMF.
PS: Pinging.... Kennedy Nyarotho, or who was that on this list who knew so much about GSM? :-)
Will help you ping some guys offlist, who'd have much more clue than me ..then you can post your "happily ever after" later.
