Device not registered

[maverick23]

This problem I am going to describe happens more often than desired, sometimes after hanging up, or other times after not using my phone at all for a long time:

When I pick up the phone, my HT701 says "device not registered" and the TEL led appears off.
I cannot use the service and I have NOT changed any configuration settings.

I tried several NAT Traversal options and it makes no difference.
The only way I found to resolve this is by rebooting the device. This is very inconvenient and happens often.

Please help.
Thank you

Hi there,

Please see below- this should resolve the issue permanently:

FXS Port:

Nat traversal(STUN) should be setup as "No, but send keep alive"- firmware 1.0.18-.1.0.43

For firmware version 1.0.43 and newer, please change it from "NO" to "Keep Alive"

Advanced settings:

STUN server is: this entry should be blank
Keep-alive Interval: should be 20.

Thanks,
