Hello Skunks,
I've been playing with an IP PBX with both analog and IP trunks.My analog lines are from telkom and my GSM units use lines from Zain and Safaricom. The GSMs use IP trunks into my PBX - Avaya IPO406. I am intergration VoiceMail Pro (from Avaya) with this PBX so that I can get an IVR with some added features - which is where DTMF comes in. Now, for 4 days I have been fighting to get this thing doing some specific call routing using DTMF with a Zain line. I even got to a point where I used an analog GSM (Fusin 100) when DTMF simply couldn't work - with a Zain line. The GSMs I use are 2N (www.2n.cz) and are super! 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 feature that they implemented and know about? Is there a reason a GSM operator would want to block DTMF on their systems?
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? :-)
