Several tenants in a East 53rd Street and lexington Avenue building had been dealing with unreliable lobby communication, so management scheduled a service visit.
Once on site, Misha began tracing the audio path unit by unit.
What he discovered
The issue turned out to be a combination of:
- aging connection points
- slightly loose handset wiring
- light oxidation at terminals

Repair steps
After re-securing the wiring and cleaning the contacts, Misha ran a full building call test.
Final check
Two-way audio was restored clearly across the tested apartments.
