Hi all, 
I am currently investigating how to pass DTMF information from the
terminal in e.g. PSTN network to a SIP Application (for voice
messaging). It seems like currently there are basically two established
methods of doing that:
- Using SIP INFO  (RFC 2976) and
- Using particular RTP Payload types (RFC 2833).
 
However the now evolving standard kpml seem to be very interesting and
if i understood correct it was supposed to be a PS July 04
- Is it still the approach that kpml should be a PS? 
- Are anyone aware of any kpml example implementation?
 
Thanks
