We use SMS API to send SMS commands to our remote GSM device, and we've ran into an interesting problem: the SMS's are sent and delivered to the remote device, but it ignores the messages. If we send same SMS from a real cell phone - the SMS command is accepted by device, but not when it is sent via RingCentral API. We've tried Rogers and Chatr SIM cards on remote device with the same result: SMS only accepted when they are sent from a cell phone and ignored when they are sent from RingCentral API. The texts look exactly the same! So what's the difference?
PS: The message contains stars and hashes (*#) i.e.: *1234567*01*45#
