Using Call Alerts
Call Alerts let you notify someone that you want to communicate
with them using PTT. When a user receives a Call Alert, pressing
the PTT button places a PTT call directly to the sender. The
receiving party will hear a tone indicating that you wish to speak
with them using Push-to-Talk. The receiving party has the option
to answer or ignore the call alert.
To send a Call Alert:
1. Enter a PTT number or select a number from History or
Contacts.
2. Press left soft key for Alert.
3. Press and release the PTT button. (The recipient’s phone
will emit an incoming tone and display an alert.)
Using Group Calls
You can start or participate in a group call with up to 50 total
participants. You can create a group call in several different
ways:
• By setting up a Group contact on your phone.
• By selecting or entering multiple numbers for a one-time call.
Once you have created Groups, you can communicate with
everyone in a group simultaneously.
Making Group Calls
Group calls can be made by selecting saved groups from your
Contacts, selecting from group calls saved in History, or by
creating groups on-the-fly.

your phone) to begin the PTT call.

to-one PTT call.
