sip peer to peer behind nat router!

Hi all

I have deployed my first uc320, any everything ok so far, ive tested the sip trunks with them on register mode and all works. But i was wondering if i could get the sip trunks to work on peer or direct mode. I have tried it and outgoing calls are fine but on incoming there is no audio. My ISP has a static address so i have port forwarding enabled for ports 5060, 5061 and ive pointed them to the WAN IP address of the uc320, do i need to forward the RTP ports as well? if so which ones, also do i tick the NAT mapping options.

Be good to know if this can be done or not, as sip peering seems to be better for bandwidth and quailty.

Thanks

Dave
