RingCentral has all of the calling and mobile collaboration features businesses look for in a phone system.

RingCentral is a cloud-hosted unified communications system that is also our choice for the best business phone service. The conference call service is just one aspect of RingCentral that makes it a useful business phone system. With the app, you can quickly tap a button to connect to the call without having to dial in to the conference and enter a PIN.

The RingCentral mobile app, available for iOS and Android devices, makes it simple to join conference calls. This is a reservationless service, which means users can host audio meetings without scheduling them in advance. With RingCentral, each user has access to their own conference bridge, which can host unlimited conference calls with up to 1,000 participants.

RingCentral is our choice for the best conference call service within a phone system because of its support for up to 1,000 callers at a time, which is far and above what many other phone systems offer.
