Is PhoneMondo - Cloud CallerID notification safe?

Low risk

PhoneMondo shows a cloud caller-ID dialog on every page and takes call commands from its vendor server over a WebSocket.

The extension connects to the PhoneMondo service to show incoming-call notifications and place calls from numbers on web pages. Its content script runs on all sites and passes messages tagged 'phonemondo' from the page to its background worker without checking where they came from. The background worker also runs server-pushed actions, such as fetching a server-supplied URL, opening tabs, and uploading debug logs.
