Phone disconnected TD call after a certain number of rings

My phone disconnects calls after a certain number of rings, and when I called customer service, she tried to say it was the radio station I was calling. It’s not. It needs to keep ringing in order for them to pick up, but my phone e cuts me off- clearly a Verizon message that comes on with , “your party isn’t picking up. This call will be disconnected now.” Anyone know how to solve this?
