SPA9000 registers very often when using STUN server

[alfonsopulido]

SPA9000 ver 6.1.5 tries to register into ITSP every second when STUN server options are set.

Register and inbound calls are sucsesful

SysLog Server shows:

I've tried with different STUN servers with same result.

Have any idea why this happens?

I just changed my isp and i'm having the very same problem.
Did you manage to find a working solution?
On my log, i see tons of the following:
