Scenario. Polycom phone, private IP address, behind Cisco router doing NAT overload to a public IP address (SIP 'fixup' disabled, so the Cisco isn't mangling anything).
RTP stream from FreeSWITCH is sent to the private, not public address of the phone.
I've got this working on 1.0.6 but I've tried this with FreeSWITCH Version 1.0.head (git-7070061 2011-01-20 13-52-00 -0600) and it doesn't seem to work for me.
I may be (hopefully) missing something very obvious here.
