Voice over USB (AT+QPCMV) on RM500Q-GL

Can the RM500Q-GL module support voice over USB like Ex25 modules?
On my module with firmware RM500QGLABR10A02M the command is rejected.

Dear customer,
The feature Voice over USB is valid on RM500QGLABR11A04.
Please contact withe the sales or the local FAE for the lastest firmware.
