[Serusers] RTP Proxy errors

[sip]

So... I followed the instructions on OnSip on how to set up RTPProxy. 

However, I made a modification because I'm running it on a different
machine... changing the 

modparam("nathelper", "rtpproxy_sock", "unix:/var/run/rtpptoxy.sock")

to 

modparam("nathelper", "rtpproxy_sock", "udp:XX.XX.XX.XX:22222")

I've run RTPproxy on the remote machine as such:

./rtpproxy -f -l XX.XX.XX.XX -s udp:* 22222

And it's running. 

I start the ser server, and I see a slew of commands hit the RTPProxy console:

received command "26742_0 V"
sending reply "26742_0 20040107
"
received command "26745_0 V"
sending reply "26745_0 20040107
"
received command "26791_0 V"
sending reply "26791_0 20040107
"
received command "26797_0 V"
sending reply "26797_0 20040107
"
received command "26748_0 V"
sending reply "26748_0 20040107

received command "26750_0 V"
sending reply "26750_0 20040107
"
received command "26751_0 V"
sending reply "26751_0 20040107
"
received command "26752_0 V"
sending reply "26752_0 20040107
"
received command "26784_0 V"
sending reply "26784_0 20040107

etc, etc ad infinitum


After a moment, the SER console spits back:

I've done a search on this on Google and found a couple of people with the
same questions and NO people responding with answers. 

Any ideas what's going on?
