Summary:                    DTMF Tones not working
Description: 
Hello,

With Asterisk version 1.6.1.11 the sending of DTMF rfc2833 tones isn't
working anymore.

But when I disable the option "Force RFC2833 Out-of-Band DTMF" on my SIP
phone it works fine.

Is this a planned change or simply a bug?

Regards,

Hendrik

Ok I just found out that;

with version 1.6.1.10 a voicetape (or whatever you call it) isn't
hearable.
So I even wasn't able to test the DTMF tones because I couldn't hear the
voicetape.

With version 1.6.1.9 I can hear a voicetape and I can also send DTMF
tone.
I've uploaded a log of version 1.6.1.9

Changes I made:

Version 1.6.1.10 I added 'parkinglot' in 'sip.conf'

Version 1.6.1.11 I added 't38pt_udptl = yes,fec,maxdatagram=400' in
'sip.conf'
