button with a short
cut to the “Call diversion” menu. Refer to 9.6 Short Cuts on page 52, and Divert All Calls on
page 43.
Depending on if the SIP or H323 protocol is used, the Call Diversion differs when the VoWiFi
Handset is out of range of the VoWiFi network. Using the SIP protocol, the Call Diversion
function is managed by the VoWiFi Handset and the Call Diversion does not work until the
VoWiFi Handset is within range again. Using the H323 protocol, the Call Diversion function is
managed by the PBX and is available in the VoWiFi Handset, also if it would be out of range.
Which protocol is used, is seen in the Administration menu in the Device Manager.
6.6 Push-to-Talk Group Call
Push-to-talk (PTT) provides instant voice connectivity to a group of persons. Push-to-talk is
a one-way (half-duplex) communication. When a person wants to talk, he presses and holds
down the button. Letting go of the button gives another person an opportunity to push-
to-talk.
In order to participate in the conference, the group members must accept an invitation
received as a text message, see 6.6.1 Accept a PTT Invitation on page 37.
If a member declines an invitation, he/she can re-join the group/conference later on, see
6.6.3 Re-join a PTT Group on page 38.
A user can also invite a group of members to participate in a conference call by calling a PTT
group, see 6.6.4 Call a PTT Group on page 38.
Note: PTT group(s) must be defined in the Device Manager, and Messaging Group(s) in the
Configuration tool (IMS3 or Unite CM), to be able to use this function. Refer to the
Configuration Manual, Ascom i62 VoWiFi Handset, TD 92675EN, Installation and Operation
Manual, IMS3, TD 92762EN, and Installation and Operation Manual, Unite Connectivity
Manager, TD 92735EN.
