The push-to-talk (PTT) function can be described as a group or conference call to a predefined group of
members. If one of the group members wants to get in contact with the others, he or she presses and holds
the PTT button to open the microphone.
By default, the Multifunction Button 1 can be used as the PTT button. The Multifunction Button 2,
which is larger than the Multifunction Button 1, may also be configured to serve as the PTT button.
Some legacy systems/PBXs require that the handset sends a predefined DTMF tone when
pressing/releasing the PTT button. For more information, refer to the Configuration Manual,
Ascom d83 DECT Handset, TD 93426EN.
To participate in the conference, the group members must first accept an invitation received as an incoming
call or as a text message. See 8.2.4 Accept an Invitation, page 56.
If a member declines an invitation, he or she can re-join the group or conference later on. See 8.2.7 Re-join
a Group, page 59.
A user can also invite a group of members to participate in a conference call by calling a PTT group, see
8.2.6 Call a PTT Group, page 58.
