Trixbox to Panasonic TDE via H323

Hi Guys

I've got a Panasonic TDE 500 connected to the latest version of Trixbox and can call between the two. The only problem is when calling from the Trixbox to the Panasonic I get one way audio from Trix to Pana.

Now I know this is caused by the Panasonic having two IP addresses (one for signalling, programming etc and one for the audio stream), I can resolve the problem by using a router but is there any way I can program the Trixbox to stream the audio to a different IP?

Thanks in Advance
