Hi, i'm having problems with DTMF, the problems are with established connections and some IVRS. When i call to other number which has an IVR, some digits doesn't work. I digit a long number (required by the IVR, at least a 10 digit number) and it doesn't work. I think it's about DTMF signalling, i've all my extensions with RFC2833 mode, i've an LinkSys PAP-2 and a Polycom 301, allowed codec is ulaw. If you need more information, pleas feel free to ask :) Cheers, Santiago
