I also tried using DTMF for a project I was doing back in 2006-2007. Like you [odhiambo] I was also using an IP PBX connected with a GSM unit The DTMF was working perfect with a safaricom line but id not work at all with a Zain line. Since i did not 'need' to use the zain line, I never raised the issue with zain [ celtel at that time I guess] engineers then. I just used the Safaricom line. It seemed to me that zain had blocked DTMF on the second leg of a call [the receiveing end] Thats was why their internal IVR systems could work with DTMF but my zain line could not. They were simply not forwarding the DTMF signals on the second leg of the call where my GSM unit lay. I could be wrong and the reason could be very different, that was just my initial thought. It seems this issue has persisted for a long time if guys are still facing the same problem. Either the zain engineers are not aware of this problem or it was set like that intentionally. Can someone in Zain please look at this issue and sort it.
Hi Philip, Zain are urging me to take up an E1 service in order to have my system working. That is a huge cost that I am not ready to incur. Your description seems to rightly point where the problem is and given the communication I am getting from Zain, I am slowly beginning to hate the operator for this simple reason. Perhaps it's time we started considering where to move our eggs as this nest is getting colder... -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "If you have nothing good to say about someone, just shut up!." -- Lucky Dube
