PTT groups

Channels

A PTT channel consists of a group of people (for example,
friends or a work team) who joined the channel after they
were invited. When you call a channel, all members joined
to the channel hear the call simultaneously.
You can join pre-configured channels. Public channels are
open to anyone who knows the URL for the channel.
When you are connected to a channel and talk, all
members joined to the channel hear you talking. Up to five
channels can be active at the same time.
Select Options > PTT contacts > Netw. grps./
channels.
To connect to a public pre-configured network group or
channel for the first time, you must first create the group
or channel. Select Options > Add existing, and enter the
required information. After the link to the group has been
created, you can attempt to join the group.

Network groups

Network groups consist of pre-configured lists of
members that are stored on the server. You can define
participants by adding them to the member list. When you
want to talk to a network group, you can select the group,
and make a call to it. The server calls each participant in
the group, and the call is ready when the first participant
answers.
