Hello, all. I've come across a nasty problem just as we are ready to put our first system into production. During our final testing, we were plagued with several "invalid extension" or "password incorrect" messages when we knew the information entered was correct. Upon investigation, we saw that DTMF signals were occasionally but not consistently duplicated. We might dial extension 1234, see 1234 on the phone from which we dialed, but see 112334 on the Asterisk console.
We have seen this from cell phones calling via the PSTN (we use a SIP trunking carrier and do not handle the PSTN interface ourselves); we've seen it from land line phones via the PSTN, and have even seen it internally from our own Snom SIP phones. dtmfmode=auto but we have also tried setting it to rfc2833 and we have tried relaxdtmf set to both yes and no. We are running Asterisk 1.6.1.6 on CentOS 5.3. We really don't know what more to do to fix it. Googling shows that others have had this problem but I haven't seen a clear resolution other than playing with relaxdtmf. How do we solve this problem? Thanks - John -- John A.
