Hey guys. I'm losing hope with my systems here.I have this question posted in both systems forums and figured i would try it here too. I have an old Executone 648 that i connected to a Zultys MX250 via a T-1. The circuit syncs up and looks like it works for the most part. I can call from one system to the other. The problem i am having is when i transfer a call from Executone to Zultys, the call is dropped. Engineers at Zultys originally told me the reason was because Executone was prepending the dnis digits with a # character. . Zultys sees the # as a delimiter character so it doesn't know what to do with the following digits. I was able to remove the # from the transfer sequence and thought that would fix the problem. It didn't. I get the same results. The Zultys guys are now telling me Executone is dropping the call. Below is a snap shot of the CAS Log of a transferred call.

Does anyone here know what it means ? The 5th line down DSP_ start_dtmf_collection is followed by 3 DTMF digits. Then "End of Dialing". What does the next few lines mean ?

I doubt that will work. Executone is a very old hybrid system. Zulus, is a IP system. Don't not work well together. Time to upgrade.
