It is tolerant. Was, rather.

However, current networks are VoIP; the house phones are handled at the 
router or ONT device, and these might not be that tolerant. My router 
does handle pulse dialing, I tested it. But I don't have any rotary

crushed them to pieces in the transition to more modern terminals.
