simultaneously.

Each member in the group is identified by a nickname, which is shown as a caller
identification. Group members can choose a nickname for themselves in each
group.
Groups are registered with a URL address. One user registers the group URL in the
network by joining the group session the first time.
There are three types of PTT groups:
• Provisioned groups are closed groups that allow only selected participants
provisioned by the service provider to join.
• Ad hoc groups are groups that the users can create. You can create your own
group, and invite members to the group.
• Ad hoc pro groups are groups you can create from members in a provisioned
group. For example, a business can have a closed group and separate groups
created for certain business functions.
