As the Subject outlines, this is the basic setup. Does anyone have any experience w/ FreeSWITCH and any session border controllers? The problem we are having seems to be related to NAT. We have several Cisco Spa5xxG phones which remotely register to a FS that is publicly accessible. The phones are behind NAT router, and begin to fail after more than 4 register.<br>I am thinking about using the SBC for a registration/media proxy, and am wondering how I would get FS and the SBC to work together. Any ideas?&nbsp;
