Recommend an IP Phone for use behind NAT
I am looking into changing my VOIP server to FreeSwitch. My current system uses Polycom SoundPoint IP 335 phones. The server has a public IP, but several of the phones are behind a variety of DSL routers that do NAT. These remote users have reported intermittent problems with one way audio. What IP desk phone would you recommend for a remote user behind a NAT router with a dynamic IP? I'm looking for something of comparable audio and build quality to the Polycoms I currently have. Thanks, Alan

We use Polycom phones with NAT and they work rather well --once you get the FS and Polycom settings right. I'll have to check the settings we're using. I'll update this thread with that info tomorrow. Email me directly if I forget. I've got enough cold meds in my blood to kill a horse... I might wake up and not remember this conversation :) Best, Gabe
I was researching a way around NATs for remote phones and came across Grandstream phones that have an OpenVPN client so that you can traverse the nat via VPN and the IP phones will be connected directly to your server. So if you don't mind running OpenVPN Server as well you might give that a try. I am thinking about buying a few and trying them out in the next couple of weeks, so I'll post my experiences when I'm done. In the mean time, if you have experience with Grandstream do chime in before I buy them :) Kerem On Wed, Feb 22, 2012 at 9:35 AM, Gabriel Gunderson <gabe@gundy.org> wrote:

Alan, We have exactly the same setup. FreeSWITCH with public IP and All polycom phones behind the NAT. We never have any issues with polycom phones. I would say check the DSL modem/routers. Most of the time these routers not working properly for sip. We always use pfsense. Lloyd On Sat, Feb 25, 2012 at 6:24 AM, Kerem Erciyes <kerem.erciyes@gmail.com>wrote:
