 supports PRACK Asterisk will activate it or support it if the other side
 requires it.
 There's currently no support for requiring PRACK in a call.
+
+In this branch there's also code for a related issue. The option "earlymediafocus" in 
+SIP.conf will, when enabled, force Asterisk to only parse and activate the first
+SDP received in an 18x answer. If multiple devices answer, the others will be ignored.
+This works better if you enable strictrtp in rtp.conf so that we lock on to the ip
+address in the SDP instead of accepting audio from anyone.
