I need to setup a voicemail button that will dial *97 then automatically enter the password and # key. I have been unable to find any reference to this.
Use a dial DTMF function and the comma. The comma adds a short pause.
For example. Program *97#,1234 (assuming 1234 is the password).
You may also need to address the dial plan.
If you are using a Grandstream UCM you can just enable the skip password button as well.
