Commax is a well known maker of video door phones and intercom systems, widely installed in apartment buildings across Russia and other post Soviet countries. The word vyzov simply means call in Russian, which is how this clip was labeled by its uploader. Its plain electronic ring became shared on soundboards because so many people recognize it from daily life at home. Unlike a composed ringtone, it signals a real visitor at the entrance, which is why editors reuse it for pranks, POV scenes and nostalgic apartment jokes online.

The Commax intercom call tone is the short electronic ringing sound from a video door phone, used for prank videos, doorbell scenes and apartment memes.
This is the short incoming call chime from a Commax video intercom, a flat electronic ring that repeats in a clean, urgent pattern. It does not sound like a phone melody or a musical ringtone, more like a building entry system buzzing to get attention. The tone is instantly familiar to anyone who has lived in an apartment with a wall mounted door phone. In videos it creates immediate expectation, as if someone is at the door or on the line waiting, and that small pause before an answer makes it useful for tension, timing and jokes.
