Since getting fiber installed, I've been having problems with my landline phone. After calling a number and getting a connection, I am unable to enter keypad touchtones. The tones either get dropped completely or only some make it through. I attached a recording which illustrates the problem. My typical use case is calling into RingCentral for a meeting. Before fiber was installed, I had no problem with calling into RingCentral. How do I get this fixed?
