The groups are registered via a URL address. A user registers the group
URL in the network by initially joining the group meeting.
There are three types of PTT groups:
• Provided groups are closed groups to whom only the participants
selected by the provider are admitted.
• Ad hoc groups are groups which the user himself can create. You can
create your own group and invite members to join it.
• Ad hoc groups can also be comprised of members from a provided
group. A company could maintain a closed group, for example, and
additionally set up other internal groups for specific corporate func-
tions.
