Summary:                    [patch] DTMF Not Recognized with Exchange UM
Description: 
I just upgraded my Asterisk 1.6.1.4 version to 1.6.1.10 and the DTMF tones
are not being recognized by the Exchange UM server. I tested out the RC
release and found that it worked in 1.6.1.7-rc1 and broke in 1.6.1.7-rc2.

What happens is Exchange UM will say to enter your mailbox number. I enter
8532 and it will say that 8 is not a valid entry. It appears Asterisk is
only detecting the first DTMF tone.

---------------------------------------------------------------------- 
I've attached constantssrc-dtmf-1.6.1.11.patch, which fixes the DTMF issue
and still keeps the random ssrc functionality. With RFC2833 DTMF the RTP
stream used to send the digits wasn't being set with the constantssrc flag.
