I have updated my Kernel and the first day it seems like my problem was
solved, but its not.

Problem : DTMF Tones occuring on every kind of channel (SIP/ZAP/mISDN)
randomly in the middle of a conversation.
Cant reproduce the Situation, but i can log them with DTMF Log of
Asterisk (logger.conf) :

May 10 15:30:19 DTMF[25551] channel.c: SIP/10-e68c : 1
May 10 15:31:00 DTMF[25551] channel.c: SIP/10-e68c : 1
May 10 15:31:50 DTMF[25551] channel.c: SIP/10-e68c : 1
May 10 15:32:25 DTMF[25551] channel.c: SIP/10-e68c : 1
May 10 17:00:33 DTMF[26110] channel.c: SIP/10-6bcf : 5
May 10 17:06:06 DTMF[26174] channel.c: SIP/30-bcc1 : 5
May 11 06:10:06 DTMF[3633] channel.c: SIP/50-e11c : 9
May 11 08:09:41 DTMF[4853] channel.c: SIP/50-a9b8 : A
May 11 08:18:13 DTMF[4945] channel.c: SIP/20-8c2f : C
May 11 08:19:46 DTMF[4999] channel.c: SIP/50-42fb : 9

The whole day long this problem appears and in the baddest case Asterisk
get a "#" or "*" and some features get started like MOH and so on.
I have disabled this features in the most cases, but still i get the
Tones while talking :-(

Please help ! Cant find any solution Internetwide !

I use DTMF RFC2833 for snom and ZAPs - INFO for my Allnet-Sips.

Will give any info if someone try to help !

Best wishes,

Stefan
