Hello, in the manual I found this option to do cross mode from the radio with URCALL/your call method as copied below.

Not all modes get connected though.

I tried:
YSF : YS32592 works
REF : REF032AL works
FCS : FCS20660 works
BM : BM2600 "open spot requested server not found"
BM : BM310 "open spot requested server not found"
BM: BM3142 "open spot requested server not found"

When I choose Brandmeister from the Open Spot control panel it connects to all the servers, but it doesn't connect from the radio.

I am on the latest beta firmware.
I do not think that I am doining anything wrong, I hope that it's the firmware.

Thanks in advance for help.

Switching reflectors/gateways using your radio
URCALL/your call method
You can switch reflectors using your radio by starting a short call to their names as the destination callsign (URCALL), like DCS001 A, or XLX001 A. Set the desired remote module as the last character of the URCALL. You can switch to gateways the same way.

The URCALL/your call method lets youe change to the following server types:

REF/XRX/Gateway: set the URCALL to for example REF001 C. Switching to REF/XRF servers or gateways this way changes the openSPOT3's active connector to the REF/XRF connector.
DCS/XLX: set the URCALL to for example DCS001 A. Switching to DCS/XLX servers this way changes the openSPOT3's active connector to the DCS/XLX connector.
BrandMeister: set the URCALL to BM followed by the BrandMeister server ID. Example: starting a call to destination callsign (URCALL) BM2162 switches to BrandMeister server 2162 (Hungary). Switching to BrandMeister servers this way changes the openSPOT3's active connector to the Homebrew/MMDVM connector.
FCS: set the URCALL to the FCS server and room number. Example: starting a call to destination callsign (URCALL) FCS00199 switches to FCS001 room 99. Switching to FCS servers this way changes the openSPOT3's active connector to the FCS connector.
YSFReflector: set the URCALL to YS followed by the YSFReflector server ID. Example: starting a call to destination callsign (URCALL) YS89804 switches to YSFReflector 89804 (AmericaLink). Switching to YSFReflector servers this way changes the openSPOT3's active connector to the YSFReflector connector.
NXDNReflector: set the URCALL to NX followed by the NXDNReflector server ID. Example: starting a call to destination callsign (URCALL) NX28299 switches to NXDNReflector 28299 (America-Ragchew). Switching to NXDNReflector servers this way changes the openSPOT3's active connector to the NXDNReflector connector.
