Group Types and Maximum List Sizes

Workcloud Communication PTT Pro for iOS

Groups organize contacts into categories or units and are created in the

Workcloud Communication PTT Pro Management Portal

or on the device. 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 be created with the ability to initiate calls, receive calls, or listen only for call monitoring. Except for Broadcast and Personal groups, groups have a size limit of 254 contacts.

Group and List Types
Group or List Type	Where Created	Description
Contact List	Portal	A contact list is created on the Portal, but the user can add or remove contacts from the device. The maximum number of contacts listed in Workcloud Communication PTT Pro is 895.
Personal Groups	Device	Personal groups are created on the device and are controlled and edited by that user, the group owner. Only the owner can call the group. Users may not remove themselves from a personal group. Users long press on a contact and select Create Group . Personal Group PTT calls are ineligible for late join. The maximum number of contacts is 127.
Member Groups	Device	Member groups are created on the device, and all members see the group on their device. Any member can make a call to the group. Members can late join a call after it has begun.
Enterprise Open Groups	Portal	Enterprise Open Groups are visible to all users. Users with appropriate priority access may join an Enterprise Open Group.
Enterprise Closed Groups	Portal	Enterprise Closed Groups are created on the portal and show on the device as an enterprise group. The administrator can make this group hidden, searchable, or available for late join.
Enterprise Dispatch Groups	Portal	Enterprise Dispatch Groups permit two types of members: call initiators and call receivers.
Broadcast Groups (Public Safety Announcement)	Portal	A Broadcast group can have up to 60,000 members. A Broadcast announcement interrupts an active non-Broadcast PTT call. The Broadcast is sent to all devices that are registered with the system at the time that the call is started. During the time that a Broadcast is active, the server will attempt to contact each registered device from the Broadcast Group for a specific duration of time to deliver the Broadcast announcement. Broadcast Calls ignore Do not Disturb (DnD) settings.
Surveillance Goups	Portal	The Surveillance Channel Group type mimics an LMR Radio, with a dedicated channel users can join and leave over time. When started, the call will stay open until a configurable time period or until the last member has left the call. Based on the group configuration, the call can be idle for up to 2 hours before the call will be dropped.

When an administrator uses

Profile Manager

, the device can display friendly group names. When this occurs, underscores in the group name are replaced with spaces, and the first letter of each word in the name is capitalized.
