Hi Frank!

Instead of adding overhead to rtpproxy to deal with this how
about setting up a bonding interface/trunk interface/... on
the underlying OS?

In a nutshell you aggregate multiple ethernet interfaces into
one virtual interface. The virtual interface gets one IP.
As part of the interface config you can define the load
distribution mechanism (everything from round robin, failover
to more complex link aggregation protocols).

Big advantage to me seems to be that you can change/upgrade
the underlying infrastructure without having to fiddle with
your rtpproxy config/source.

For FreeBSD check the if_lagg or ng_ether modules depending
on the version you use, i.e.

I hope this helps,
 Hendrik
