Overview of Group Types
Group calls are preset groups that are created in the admin portal or on the device. They are created as groups in the portal and will appear as channels or groups based on the feature keys selected for the individual devices in your organization. Once created, groups can be assigned to channel numbers in the Channel Tab.
In addition to the method of group creation, groups are customizable based on visibility, access, and call behavior. Depending on the type of group, members may created with the ability to initiate calls, receive calls, or listen only for call monitoring. With the exception of Broadcast groups, all groups have a size limit of 250. To see instructions for group creation in the Admin Portal, click here.
Types of groups:
| Group Type | Where Created | Description |
| Personal | Device | Personal groups are created on a single device and are controlled and edited by that user, the group "owner." Only the owner can initiate a PTT call the group. Members will not see the group listed on their devices. To create a personal group, long press on a contact (Android) or select the plus sign (iOS). You must have this option configured for your device. Personal group PTT calls are ineligible for late joining. |
| Member | Device | Member groups are created on a device, and all members will see the group listed on their devices and anyone can initiate a PTT call to that group. To create a personal group, long press on a contact (Android) or select the plus sign (iOS). You must have this option configured for your device. Members may late join an in progress member PTT call. |
| Open | Portal | Open groups are publicly searchable for non members Users with appropriate priority access may late join an open group. |
| Closed | Portal | Closed groups are not searchable for non members. |
| Dispatch | Portal | Dispatch groups permit two types of membership: Call initiators and call receivers. |
| Custom | Portal | Custom groups are groups that have an adjustment to the settings for standard members: deselect the join call option, or making the group searchable or not; add a listen only group; allow for alert on call start; or configure for a large group. |
| Unicast | Portal | A unicast group provides an announcement function. |
| Surveillance | Portal | The Surveillance Channel Group type mimics an LMR Radio, with a dedicated channel that users can join and leave over time. Once started, the call will stay open until a configurable time period or until the last member has left the call. Based on configuration, the call can be idle for up to 2 hours before the call will be dropped. |

Types of Group Membership: Originate Only, Receive Only, or Listen Only
Some groups configured in the portal may have members with limited roles in group communication. A user my be assigned the role of a call originator, a call receiver, or a Listen Only Member. Once a call has begun, a Listen Only member may "Press to Listen" to monitor a call. In the case of group members who have listen only memberships, they will get an error message that no call is currently in progress when they attempt to initiate a call to this group, and will instead be offered the chance to send a text message to this group.
