Come to think of it, I don't even know if this is entirely possible
with rtpproxy. In order to forward packets between interfaces it
appears that "bridging mode" is required, and in order to activate it
two listen addresses must be specified - but only two, and not more
than two.
I just figured I would try it with 5 by binding it to 0.0.0.0 and
seeing what happens.
Not sure how to get around this without using MediaProxy, which seems
both increasingly incompatible with Kamailio politically and also
requires a slew of Python dependencies that are difficult to install
on a CentOS host that I do not really administer. If this were a
Debian box like my systems, it would be easier.

The reason I need to do this, by the way, is because I
have a host with
5 network interfaces and depending on where the media is going the
source IP of the media needs to be different. But there are too many
possible combinations for me to just put all of the possible scenarios
statically into the configuration, and it's not clean; I need it to be
dynamic and query a database so it can be changed on the fly.
Any suggestions for workarounds that allow me to use rtpproxy are welcome!
Thanks,

It's very frustrating that some functions
don't accept pseudovariables
and there's no workaround.
For example, in this case I need rtpproxy_offer() and
rtpproxy_answer() to accept an IP address argument that is retrieved
from a database. However, this won't work.
rtpproxy_offer("", $var(src_ip)); # Config compilation error
rtpproxy_offeR("", "$var(src_ip)"); # Results in $var(src_ip)
# literally being placed in the
# SDP body.
I understand it is difficult to go back and update all legacy
functions to accept PVs everywhere. But isn't it possible to provide
a wrapper/compatibility function in the core that will parse a PV and
generate as a result something that other functions can see as a
string literal?
