When marking a 3-way phone call, party gets a choppy/helicopter voice. We all have Verizon and no issues when on a "one on one" call. Once you add a third person, at random points, they can get choppy or myself. One individual has already got a new phone and still nothing. A couple of us have apple and a couple have android and can not pinpoint and exact issue other than possibly a bad switch on the network side. At some points we have up to 6-8 people on a conference and someone gets this choppy like signal. If they hang up and call back into the party, it clears up. Anyone else experience this and possible steps to resolve as this is affecting business. Thanks
