I’m trying to follow the instructions in http://community.wowza.com/t/-/46 (Using native RTP encoder…).
However, since the P3301 doesn’t have an sdp file anywhere that I can copy, what I’ve done is started up VLC in from a terminal window and then connected to the camera’s stream with VLC. This allows me to see the SDP info in the terminal window, copy it, and make an SDP file out of it.
I read that I had to modify the SDP file a bit, and it worked for me modified last week, but the same file from last week is not working this week 
Here’s what the SDP file looks like before modification:
v=0
o=- 983527116251980 983527116251980 IN IP4 CA.ME.RA.IP
s=Media Presentation
e=NONE
c=IN IP4 0.0.0.0
b=AS:50000
t=0 0
a=control:*
a=range:npt=0.000000-
m=video 0 RTP/AVP 96
b=AS:50000
a=framerate:15.0
a=control:trackID=1
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1; profile-level-id=420029; sprop-parameter-sets=Z0IAKeKQPBf8uAtwEBAaQeJEVA==,aM48gA==
I tried setting the port in the m line to the port that I use when accessing the camera’s RTSP stream, and it hasn’t worked yet.
