I use 2talk as a VoIP provider.

Most star codes for changing 2talk features settings via the phone work find. However, *72 and *92 which related to call forwarding settings doesn't seem to work on NetComm NF4V.

For example, the below *73 and*93 work as expected but *72xxx or *92xxx do not do anything. I believe these star codes are reserved or preset by NF4V.

*72xxx Call Forward Always Activation
*73 Call Forward Always Deactivation
*92xxx Call Forward No Answer Activation
*93 Call Forward No Answer Deactivation

Is there anyone know how to disable these star codes on NF4V?

Thanks in advance.
