Door calls on FRITZ!Phone handsets
Many homes already have a FRITZ!Box and FRITZ!Phone DECT handsets. frogTerminal registers over SIP so the doorbell rings those handsets directly — no extra indoor station required.

Typical workflow
Answer the door on the handset you own
frogTerminal registers as a SIP device on the FRITZ!Box. When a visitor rings, the FRITZ!Phone DECT handsets ring; the resident answers with two-way audio and can release the door — using telephony that is already installed.
