Unfortunately, no. I don't. I used to have the problem a lot, but now I don't
as much and I'm not sure why it eventually went away. During that period of
time, however, I was also having some network issues.
SEMS is doing exactly what it's supposed to do, really, in that it's detecting
the DTMF signals... the question is whence come the signals, and that seems to
be a basic issue with the encoding/decoding of the voice.

Hi N,
Yes i have tried on different RTP codec but is the same is very senstive.
I have tested on G729 and G723 is slightly better but when i raise
my voice abit the unknow DTMF is still detected. Do you have better suggestion?
Thanks.
rdgs,
nicky

Have you tried a different default RTP codec?
I have this problem with G.711u and G.711a on occasion, but beter with
G.729
or G.723.
I'm not sure if it's a codec issue or an encoding issue, but I've seen it
happen in straight voice calls. If someone's loud on the other end, it
converts that noise into a DTMF signal.
