Empty incoming exactly every 15 minutes on TDM400P

Question

Asterisk

I've run out of ideas, and there's a beam in my eye.

The incoming analog signal comes from the landlord's PBX... like Avaya is old there... CallerID won't even send.
Normal incoming outgoing runs, all the way through, but every 15 minutes an incomprehensible incoming one that they never have time to answer.

in console

Has anyone experienced this behavior?
