To call multiple Security Center users at the same time, you can create a basic ring group by simply assigning a SIP extension to a Security Center user group.
A basic ring group is a Security Center user group which has been assigned its own unique extension. In a basic ring group, you can only include Security Center users and other Security Center user groups.
What you should know
- Log on to Security Center with Config Tool, and then open the User Management task.
- Click User groups, and then select one from the list.
- Create a Security Center user group that contains all of the users you want as part of your ring group.
Click the VoIP tab.
The members of the user group appear in the Call list field.
Assign a SIP extension to your ring group in one of the following ways:
- Click Auto-assign. Auto-assign automatically assigns the SIP entity the next available phone extension in a given range. As a result, it is the recommended way of assigning a SIP extension to users, ring groups, and SIP intercoms. Simply click this button, choose an existing range, and then click Apply.
- Enter the following:
- SIP extension
- The SIP entity's phone extension. To be able to communicate with other SIP endpoints, every SIP entity (user, ring group, or intercom) in Security Center must have a unique SIP extension assigned to it. Either enter the extension manually, or use the recommended approach of clicking Auto-assign.
In the Call
field, select one of the following:
- All at once
- All members of a call list are called at the same time. The call stops ringing once any one of the members within a call list answers the call.
- Successively every
- Members get called one after another in sequence, with a set delay between each call. The order in which the members are called is based on the order in which they appear in the call list. This sequence of calls is repeated until any one of the members within a call list answers the call. If a member declines the call, the next member in the call list is immediately called, regardless of whether the set delay between calls has elapsed. The minimum delay is 10 seconds. Because it might affect how long a call to a ring group goes unanswered, it is not recommended to set a delay that is too high.
- (Optional) To change the order in which the members of the ring group are called, use the arrow buttons to move the members up or down. This is available only when Successively every is selected.
- Click Apply.
As shown in the image below, this basic ring group includes five Security Center users, each with their own dedicated extensions. The call sequence for this ring group is set at Successively every 10 seconds. As a result, when the ring group extension (7002) is called, Charles' extension (6001) is called first. If Charles does not answer or decline the call within 10 seconds, Clive's extension (6002) is called. The same sequence continues until one of the members in the call list answers the call.
