After the radio is connected to a WLAN or cellular network, you can initiate a call through the PoC application.

Select a contact from the contact list or recent call list.
Enter a contact number in the dialpad.

For a half-duplex voice call, press and hold the PTT key to speak, and release the PTT key after
finishing speaking.
For a full-duplex voice call, speak directly without pressing the PTT key.
If you set the standby group, you can initiate a call to the group directly.
