A Call or Ring Group feature allows a business to have their incoming calls redirected to different destinations that are included in that call group, where a member of the group will able to answer. In other words, call groups allow for grouping a number of extensions together to share receipt of an incoming call.

In the event none of those members get to the call, a voicemail is assigned to take a message, which those members typically all have access to. Call groups are most handy for assigning an incoming call to a department where all employees have the same, if not similar roles and resources within the company to address and resolve an issue.

Types of Ring Patterns for Call Groups:

Cyclic Pattern – Also known as “roll over” and allows equal distribution of calls, making sure all extensions in the Call Group get their turn in answering the calls. You can choose how many times the call cycles through the extensions before sending calls to your no answer destination.

Sequential Ring – Distributes calls among all extensions in the group in the same order that the extensions are listed. Each new call starts at the first extension in your list. You can choose the number of times the call cycles through the extensions before sending call to your no answer destination.

Simultaneous Ring – Rings all extensions in the group at the same time. The first extension to pick up the phone will answer the call.
