I'm trying to use "inbound-bypass-media=true" in sip profile internal.xml, however when I do this I can not get any voice on caller side, considering that both devices are behind a NAT(in the same private network), and my FreeSWITCH has a public IP as below.

[FreeSWITCH]-->internet--->{NAT}--->Phone1

                                                      |--->Phone2

Your kind help will be appreciated.
