Hello,

Trying to use an additional handset for a W52P.

The primary handset works great. De-registered both handsets and tried registering secondary to H1.

When attempting to place outbound calls the phone reads, "VIA-IP Not Available" with a red X.

Does this mean that the new secondary handset is not compatible with the base station?

Thanks.

If the additional handset is a W52H then it sould work.
Other type of handsets are not allowed.
