Invitation Received during an Ongoing Call
If a user receives a PTT invitation during an ongoing call, the call is disconnected and the PTT
call is started automatically if the following conditions are true:
• The handset is configured to answer invitations automatically.
• The invitation has higher priority than the call priority.
• The user does not reject the invitation within 10 seconds.
When the invitation is received, a warning signal notifies the user before disconnecting the cur-
rent call in order to connect the PTT call.
NOTICE:
Depending on the priority of the invitation, the ongoing call might be
disconnected immediately or after 10 seconds.
If the user rejects the invitation, it is possible to re-join the PTT later. For details, refer to the
