Ooma Forums

we use a panasonic phone system with a base and three additional handsets that plug into electrical sockets. will the additional handsets work with ooma right out of the box or is additional setup or equipment required?

Telo handsets work once you register them to the Telo base.
A pin from your my.ooma account is needed to complete the registration.
The Telo supports a maximum of four handsets.

All the Panasonic handsets will work with the Telo, but will only utilize one line, except for call waiting. In order to use the instant second line you must have a Telo Handset.
