Looks like sipdroid is doin SIP INFO to implement DTMF. This method is not 
supported by 
majority of the VoIP service providers. Need to implement inband DTMF or 
RFC2833. Are 
there any plans to do down that path.

I have created another patch to support outband DTMF (RFC2833).
This also include small bug fix to codec selection mechanism (issue 232).

Pmerle, could I check-in this patch?

The code needs a few changes before checking in. It should test if rfc2833 is 
supported 
(as it already does) and when true, don't send SIP INFO packets for DTMF any 
more.

The RFC2833 packets itself look differently than those sent by asterisk. Are 
you sure 
it is correct to send out 9 packets, not a total of 6? Also stop/start 
recording and 
sleeping should not be necessary for sending these packets.

(Reply to comment 6)

I have committed to r436 and r437.

With r437, SIP INFO will not be sent when rfc2833 can be used.

The packets are very similar to packets that X-Lite sends.
Number of packets to be sent depends on a duration of a DTMF event.
The duration is now 120ms (6 packets and 3 end packets), but can be changed to a
shorter period.

Stop/start recording may be unnecessary if record.read() ignores mic input 
during
DTMF packets being sent.
