During the day we receive 2-3 caller id displays on the TV per hour. Every one are unrecognizable to us. These do not show in the call log provided by Verizon.
Test calls we have placed from our cell phones to the FIOS Digital Voice line ring, display correctly, and show in the call log.
This behavior started when we upgraded to FIOS TV One equipment earlier this month.
I have captured inbound UDP packets arriving for the STB on port 63145 from the FIOS service node (18.214.209.84). Both the real calls and the bogus caller id displays are produced by identically addressed packets.
Why is the Verizon service node sending caller id display packets for calls that do not ring ?
