In order to use the Handsets, the extension number and the password for each Handset
will need to be registered in the SIP server build in the HUB board in the
Communication unit.
The same extension number and password will need to be registered in the Handset,
which will be the client device.
In other words, calls will not be available unless the extension numbers and the
passwords correspond to each other between the SIP server and the device.
Analog devices are also required to be connected to the SIP server via the analog phone
interface: SIP Phone, to have the TEL port services (TEL, FAX) registered in the SIP
server.
