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

Corresponding output of rtpproxy is:

rtpproxy: session on port 35000 is cleaned up
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.

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.
