Feb 28, 2017 · When we receive a phone call, the main phone starts ringing, rings 4 times, then it diverts to the next one and after 4 rings to the third phone. Only after this it goes to voicemail which has now been probably 45-second wait.
I can't get to the phone before it goes to voicemail. I understand that the number of rings the caller hears is controlled by my carrier, Verizon. My husband has a Samsung Galaxy S7 purchased from Verizon and when he calls, he hears 8 rings then it goes to VM. Note that I called Verizon and they set it to 8 rings, the maximum available.

Depending on which Android phone model you are using, you can dial the carrier code and directly stop the Voicemail service.
