asterisk users - Apr 2009 - Off-topic: SIP DTMF most supported method

Hi,

I know it is a bit off-topic, but I'd like to ask the community what is the
current most supported way to deal with DTMF?
I'm looking for an all-SIP system and I'm mostly interested in the end
devices support of the different methods (DTMF in-band audio, DTMF RTP
telephony events packets, SIP INFO, ...)

Thanks in advance.

It's SIP in rfc (RFC2833) then SIP INFO and then if you can't do
anything else inband audio (only G711)
