I´m looking for one node which just can make a SIP call to fritzbox.
Or any other solution.
What i want to do:
Just simple: one ESP ist connected to 2 Door Belt.
If button pressed esp sends a mqtt comand to ring.
Node red get this information and send a sip call to some of the phones in the fritzbox.
of course i can see if door one or door 2 is calling.
the best solution would be, i could totaly use the doorbelt setup in the fritzbox.
who know if something like this exist and how to do ?.
