I was wondering what are the values for sending dmtf
via sip info.
I mean, when I use dtmf relay via sip info, the sip/sdp message
contains a Signal=X where X is the dmtf.
That's ok for dtmf 0-9 . but what when dtmf is * or # ?
we must send signal=# ?
I ask that because I noticed that budgetones phone sends out
* as signal=10 and # as signal=11 . but asterisk
don't detect them, 'cause it get only the first digit of
10 or 11 ... resulting into bad * or # detection, since
they're picked up as 1 .
So I think asterisk expects a signal=* or signal=# .
but, who's right? asterisk or the budgetones?
I haven't found any doc on the net that reports what values to use...

They start out with: Event encoding (decimal) _________________________ 0--9 0--9 * 10 # 11 A--D 12--15 Flash 16 and go on from there for other events. I don't beleive * currently support any more than the above. -JimC

I'm working with Martin at Digium on it. It's good to know it's not just the Audiocodes :-) -rt -- Ryan Tucker Network Engineer NetAccess, Inc. 1159 Pittsford-Victor Road Bldg. 5, Suite 140 Pittsford, New York 14534 585-419-8200 www.netacc.net
