[BUG?] Teltronika RUT200 API send_ussd drops data connection

Hi all,

I’ve noticed an issue while testing USSD commands through the Teltronika API using an OpenVPN connection.

When I run a USSD command call, the Teltronika disconnects the data connection of the VPN.

Is this suppose to happen?

Firmware version:RUT2M_R_00.07.13.1
