For various reasons we've elected to go with Porta/Maxim Sobalov's
rtpproxy as opposed to the MediaProxy code; however, we would like to
know if its possible to do any of the following with rtpproxy or if we
should consider going to MediaProxy instead
1) Multiple Load Balanced rtpproxy servers
2) Voice path fail over, so that if we lose 1 RTP proxy the call
continues on another.
I was thinking 2 could be implemented using an OpenBSD/CARP
FreeBSD/CARP type of scenario, where 2 rtpproxy servers share 1 IP
address; however, OpenSER would need to set up an rtpproxy session on
BOTH servers to accomplish this and the OS can do the rest.
Any opinions or comments are welcome.

Hi Daniel,
1) Multiple Load Balanced rtpproxy servers
nathelper/rtpproxy has load balancing support (multiple rtpproxy via udp)
see: http://www.openser.org/docs/modules/1.2.x/nathelper.html#AEN131
2) Voice path fail over
not supported yet ...
With your approach, openser/nathelper will setup an rtp session on the
active rtpproxy (using the HA IP). The master rtpproxy will need to
be modified to update the slave rtpproxy with the mirrored rtp session
(update = create,keep_alive,destroy rtp sessions).
If you want openser to keep track of both rtpproxy servers (master and
slave), then you will need to modify both openser and rtpproxy and
distribute the intelligence ... I think this approach is more
complicated ...
Regards,
Ovidiu Sas
