It compiled and functioned to relay media stream. It's great. However, there is some error message from Ser:

Corresponding output of rtpproxy is:

I am making the test on Linux 7.3. Both of the SIP UA is ata186. The network structure is: ATA 1------------NAT 1 (Microsoft ICS)-------NAT 2 (Cisco 2600)--------SER (192.168.0.1) (192.17.1.0)
ATA 2------------------------------------------NAT2(Cisco 2600)--------------SER (192.17.1.0)
I'll make further test through Cisco 53 to PSTN.

I've applied a fix. Please update and let me know if it helps or not.
Thanks!

The call is made from a Nated ata186. I got the message from rtpproxy:
rtpproxy: can't accept connection on control socket: Invalid argument rtpproxy: can't accept connection on control socket: Invalid argument
The corresponding Ser output:

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
find
rtpproxy. 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:
