We are getting reports from the receptionist that callers are having dtmf problems (131 gets read as 113, 117 read as 111) - first digit recognized twice, third digit not read at all). I have tried 6 different analog phones, two cell phones (on two different networks), and a digital phone behind another pbx. I can't reproduce the problem at all. Switch layout: {Channelized T1} -> [Adtran Total Access 624] -> {POTS} -> [Merlin Legend Switch] -> {POTS} -> [Carrier Access AB1 w/ 8 FXO] -> {T1} -> [TE410P] I would just dismiss the problem, except that the recpetionist hears about it atleast twice a day. Most of the callers are either on POTS or cell phones (we're a school district, it's parents that call/complain). Has someone been able to reliably reproduce this problem? Is there an analog phone that will repeatedly do this? I do have 'relaxdtmf' turned on. Many thanks, Steve
