Modern wireless routers like a AVM FritzBox also include telephony features like a DECT base station and VoIP connectivity. Consequently, an incoming call can be routed to the DECT and VoIP phones in parallel. This tool acts as a VoIP phone using the SIP protocol and just shows a small notification for every incoming call. Hence, you can immediately see who is calling without having to look for your DECT phone.

Usage example:
sip-call-notify -s sip.server.com -u my_user -p my_password
-f "echo displayname: %s username: %s (From: %s)"
