[Kernel 2.6.26][rtp/rtcp]

[Alexandre Moore <alexandre.j.moore@xxxxxxxxx>]

Hello there,

I am currently working on a linux kernel 2.6.26 box with linked to 
multiple ISP (so one or more ethernet connections) and specific ones for 
VoIP usage.
What i want is to restrict SIP rtp/rtcp to specific interfaces 
(load-balance) and I can only use iptables rules kernel modules or hack 
the kernel itself (for resource purposes).
My problem is that I have two different servers for sip rtp (port 5060) 
and sip rtcp (random port 10k+).
So when the rtcp connection is established, it is not related/expected 
to the rtp and I can't track it with iptables. (callback 
ip_nat_sip_expected in net/ipv4/netfilter/nf_nat_sip.c is not called).

box ----- > rtp server xxx.xxx.xxx.1
       \-----> rtcp server xxx.xxx.xxx.2


I am doing it wrong ?
Is there a kernel module that I missed ?
is this kind of trivia is dealt differently with more recent kernels ? 
(maybe i can convince my boss to upgrade).

Regards.

(French IT dev here, so sorry if english is a bit awkward).
