No Voice - IPO 500 to IPO 500 via internal SIP trunks 2

[4946]

We are trying to link two IPO 500's via internal SIP trunking. The trunks are set up to appear as SIP provider to the other 500. At this time we have them in the same network segment (192.168.nn.). SIP call set-up occurs and the phones ring at the appropriate destination, but the RTP voice packets aren't making it. Sniffer captures indicate "destination unreachable" for the RTP packets. We have successfully set up SIP tunks from both systems to GTEL SIP trunks, so we believe that the basics are covered properly. Any suggestions on what may need tweaking?
Thanks,
4946

Vendor came in and broke it yesterday. They tried to turn on STUN and put values in address fields. Took everything back out and turned off STUN feature and it started working again.
