Start rtpproxy with `-f' flag which will prevent it from going into the daemon mode, make a test call and send me rtpproxy's output.

Hi Maxim,
I made the test. There is some problems:
The source of RTP proxy did not compile. I replaced Makefile with Makefile.linux. The following error message is given: cc -o main.o -c main.c main.c: In function `setbindhost': main.c:83: structure has no member named `sin_len' make: *** [main.o] Error 1
I commented line 83 in main.c and it compiled and the executive run.
2 I run ser with the example script rtpproxy.cfg (modified to work in my network). rtpproxy is also started. I made a nat call and here is the debug message:

In fact, it should not work because I did not tell ser how to findrtpproxy. But I did not find any information to do so.
- In rtpproxy.cfg, I found the following script:
if (search("User-Agent: Cisco ATA.*")) { setflag(1); # remember this is ATA force_rport(); fix_nated_contact();
What force_rport() is for? And in which module is it defined?
There is two option or parameters for rtpproxy. rtpproxy: usage: rtpproxy [-f] [-l address]
Is there more information about its usage other than message above?
In README of module nathelper, I found:
Name: fix_nated_sdp() Params: mode - 0x01 (add direction=active), 0x02 (rewrite media IP address with source address of the message) Desc: Rewrites SDP body in accordance with mode flag Example: if (search("User-Agent: Cisco ATA.*") {fix_nated_sdp(3);};
Does fix_nated_sdp(3) means direction=active and rewrite media IP address with source address of the message? And what does direction=active means?
And:Name: force_rtp_proxy Params: none
So what does mean?
Your reply is so soon, Maxim.

Folks,
Today I've updated nathelper module to support RTP proxy. It would be nice if somebody can test it on platforms other than FreeBSD, because I don't have an access to such boxes right now. The RTP proxy itself can be downloaded from:
https://demo.portaone.com/~sobomax/PortaSIP/rtpproxy/
Any feedback is greatly appreciated.
-Maxim P.S. I've committed it to the HEAD, those with 0.8.11 prerelease please apply the following patch:
