Incoming PBX call A telephone call may be answered while in a PTT call session. To during a PTT call announce an incoming call, the WT will ring with a low-volume

ring and display the system message.

To answer the call, press Start Call. The PTT call session will be pre-empted and no PTT audio will be heard.

After the PBX call is over, press End Call as usual to go back on hook, at which time PTT goes out of pre-empted mode and becomes active again. If an already active PTT call has not ended, the PTT audio starts playing again.

If the user does not answer the telephone call by pressing Start Call, the PTT display will be shown after the ring has stopped.

Making a PBX call To start a telephone call during a PTT call session, press the Start during a PTT call Call key. This causes the two-way radio to be pre-empted as

described above.

Incoming PTT call The PTT “receiving alert” sound will play softly in the speaker during a PBX call audio, if a PTT session is started during a PBX call. You may

continue your PBX call normally, or you may switch to the PTT call by ending the PBX call by pressing the End Call button.
