I updated my S21 Ultra last week and now it can't buzz anyone through my HOA security gate.  Someone calls from the gate, I talk to them, and press 9 to buzz them in.  Pressing 9 no longer works to buzz guests in since the update.  We have not altered our software at our gate.

This isn’t an uncommon issue.  Manufacturers are stealthy eliminating DTMF tone support in their devices.  This needs to be updated in the intercom system.  I used to have that issue with with the intercom here.  DTMF is what is used for landlines, which are getting close to being non-existent.
