• A rejected/ignored PTT invitation can be used to rejoin the session later (as long as the
session remains active), see 5.7.4 Rejoin a PTT Call Session on page 41.
• A group of users can be invited to participate in a PTT call by starting a session, see 5.7.5
Start a PTT Group Call Session on page 42.
NOTE: PTT sessions must be defined in the Device Manager, and messaging groups in the
Unite CM/Unite CS configuration tool. Refer to the Configuration Manual, Ascom Myco
Wi-Fi and Cellular Smartphone, and the Configuration Manual, Unite Connectivity
Manager/Configuration Manual, Unite Communication Server. For further details
about push-to-talk, refer to the Function Description, Push to Talk.
5.7.1 Join a PTT Call Session
NOTE: A PTT session invitation can be configured to be automatically accepted by the
handsets in the group. Refer to the Configuration Manual, Ascom Myco Wi-Fi and
Cellular Smartphone for details.
An invitation to join a PTT session can be received in two ways:
• As an incoming call (see 5.1 Answer or Reject a Call on page 29).
• As an alert message (see 7.4 Alert Response Options on page 51).
Both PTT invitation types includes a description and ways to join the session.
To Accept a PTT Invitation
1 Accept the incoming call, or tap Join, on the alert message, to accept the invitation
and join the call.
NOTE: The handset can accept the invitation automatically, start in mute mode, or
start in loudspeaking mode, depending on the configuration of the invitation.
2 The handset is connected to the PTT session, and the push-to-talk call screen is
shown. See 5.7.2 Use the PTT Call Screen on page 40 for instructions on how to use
the call screen to communicate in the PTT session.
NOTE: Invitations disappear from the screen, if not accepted within 60 seconds. All
previously received invitations are stored in the alert view, and can be joined later (as
long as the session remains active), see 5.7.4 Rejoin a PTT Call Session on page 41.
Accept an Invitation During an Ongoing Call
If a PTT invitation is received during an ongoing call, the call is disconnected and the PTT
session is connected automatically, if the following conditions are true:
• The invitation is configured to be accepted automatically
• The invitation is of higher priority than the priority of the ongoing call
NOTE: When a PTT invitation has the highest possible priority level (priority 1), the ongoing
call is always disconnected immediately.
If the priority of the PTT invitation is lower than the ongoing call, or if the invitation is not
configured to be accepted automatically, the invitation must be accepted in the same way
as a regular PTT invitation (see To Accept a PTT Invitation on page 39). If the invitation is
accepted while the call is still ongoing, the call is automatically disconnected.
