Folks,
I've just updated rtpproxy tarball available at
http://www.portaone.com/~sobomax/rtpproxy.tar to include ability to
alter location of the command socket (userful if there are multiple SERs
running on the same machine, appropriate patches for nathelper were
commited into trunk some time ago), as well as an ability to set
specific TOS for RTP packets (default is now 0xa0), which can be used to
do QoS.
Regards,
Maxim

Small correction: I've just changed default TOS to be 0xb8, which is
used by default by Cisco VoIP gateways.
I've also added new feature - "double RTP mode" (off by default), in
this mode each incoming RTP packet whose size is below some pre-defined
threshold (128 bytes) gets re-sent twice, which can improve QoS on lossy
links. Threshold here is to disable this feature for non-LBR codecs. I
like this feature from my SpeakFreely days. ;)

Thanks Maxim,
We just tested the "double RTP Mode" with Grandstream Phones and Cisco ATA 186
terminals. The Grandstream phones seem to handle it pretty well. The Audio
Quality is perfect using both modes. On the other hand, the ATA186 seems to
choke with the double rtp mode. The audio quality significantly degrades
when using this mode. The ATA186 rtp stats also start showing high packet
loss.
What phones did you test this mode with?
Regards,
Andres
