Hi Jan and Maxim:
Maybe you can help me with this.
I'm using Debian sarge r3.0 and SER apt packages (0.9.6)

I was looking at the CVS Repository if there was something related to 
this behavior with RTPPROXY and I found the following annotation for 
ser/rtpproxy/main.c on July 4:

Since we are now opening control socket in non-blocking mode, there is
race condition between accepting stream connection on unix domain
socket and availability of data on the socket. Patch it by doing read()
in a loop until we actually get the data. While I am here, allow V
command to take extra argument, which we don't process but put into
the log file. This allows to pass some extra information from the
client (SER in this case) such as PID number for example.

Does it have something to do with my problem? BTW I found a bug posted 
too at the lists.debian.org:
Bug#356721: ITP: rtpproxy -- RTP proxy for SER 

Am I doing something wrong with my installation/configuration or is it a
