USSD problems with MTK 0828

6 years 11 months ago - 6 years 8 months ago #10213 by jorgepy
I'm having problems sending USSD with a VS-GW1600 with 5 modulos (20 ports).

The problem is when trying to send the second command, the commands fails every time.

Specifically the problem only occurs with the modules that have the GSM Module Revision: MTK 0828
On the same Gateway I have also modules with GSM Modulo Revision: 1224B02SIM840W16_OPENVOX and run smoothly with the same secuence of commands.

I need to send USSD commands from all of my 20 ports. I've tested from Web UI, CLI (ssh) and AMI Interface, with the same results.

I would greatly appreciate a solution to this problem.

Best regards!

Hi Linda

The problem persist in the same way.

Even adding 30 to the end of the command. the second command is always fails and does not allow me to continue.
