Hi, recently someone was mentioning an issue with DTMF here, but there was no solution. I have a similar problem, when calling Freeswitch from my cell phone (via a SIP provider), sometimes DTMF is not recognized (read app doesn't terminate). I could not find any regularity in this, sometimes it is recognized just fine, sometimes I had to wait for the file to be played etc. The important thing to note is that when using a SIP softphone (X-Lite) I have never had this problem, DTMF is recognized perfectly. So it's probably related to GSM or something. I was wondering whether anyone experienced the same and whether there is something I can do about it. There are a few DTMF-related variables in the config files (dtmf-duration, pass-rfc2833, rfc2833-pt, dtmf-type, default_dtmf_duration, max_dtmf_duration) and I played with them a bit, but I don't really know what I'm doing.. Couldn't find any docs, either. Any ideas would be appreciated. Jan Kubr
