on the OpenSky network, voice calls from talk groups in the active profile will be audible.

Fixed:

a. If the received talk group matches the selected talk group, then the alias (if

available) or user id of the incoming caller is displayed.

b. If the received talk group does not match the selected talk group, then the received

talk group name is displayed

 When the dwell display is set to received talk group and the scan mode is None:

a. If the received talk group matches the selected talk group, then the alias (if

available) or the user id of the incoming caller is displayed.

b. If the received talk group does not match the selected talk group, then None is

displayed.

 When the dwell display is not set to received talk group, then there is no display

indication of an incoming call.

7.19.2 Transmitting a Voice Call

Transmit a voice call as follows:
