I have´nt really followed this tread, but ser can use more then one
rtpproxy. Because, you can loadbalanse with rtpproxy useing the
(atleast) cvshead nathelper module.

just remember to make sure you dont mix up what signalling goes via what
proxy :)

(Ps, see under for explination from nathelper.c)

 *              by the index (starting at 0) of the node in the

force_rtp_proxy("N1") will

 *              unforce_rtp_proxy(1).
 *              Since nathelper is not transaction or call stateful,
care should be

is selected.
