What's in this update
Added a “Dst callsign for cross calls” setting to the D-STAR settings.
This callsign will be used as the destination callsign for calls to the D-STAR transceiver coming from the network.
Added a “Cross mode destination DMR ID” setting to the DMR settings.
In case a DMR network is connected in a non-DMR modem mode, and the “Use cross mode destination DMR ID” checkbox is checked, then calls to the DMR network will be sent to the DMR ID specified at the “Cross mode destination DMR ID” field, except when using the Homebrew/MMDVM connector (it has a “Route cross mode calls to ID” field, and it will always be used).
RSSI data is now sent to the Homebrew/MMDVM server in cross mode operation.
Fixed sending empty dst/src callsigns to the server on C4FM call end Various smaller fixes
