[Freeswitch-users] FreeSWITCH -- Router -- WAN -- Router -- OpenSBC -- Several Remote Spa5xx

[Michael Jerris]

I have never seen any nat issues with SPA5xx phones in the field and we have many deployed.  Can you nail down why they are failing?  Try adjusting nat params in the SPA configs such as keepalive.
