My extension (200) keeps getting a call, from my extension, and there is no one there; it happens randomly at all times of the day or night and the call is not in the CDR. It’s really odd as the call is coming from my extension (or at least it has my ext # on the display).
indeed - depending on the model of phone you need to secure the invite source in whatever manner prescribed by the vendor; google
stop ghost calls makeofphone
for the S series devices of sangoma that endpoint template option is:
Anonymous Call Rejection Enable / Disable Configure whether anonymous calls are rejected. Stops sip attacks that cause phones to ring, but will also block restricted numbers.
