To dial a number, first dial the number, then press the # key to start the call. You may also dial the number then lift the receiver to start the call.
To hear your extension, dial *65. (Note: Press the # key to start the call.) Your extension will be the default password for your voicemail. If your phone is an older Grandstream model (GXP1415), press the key below VMsq on the screen to dial your voicemail. If your phone is a newer Grandstream model (GXP1615), press the envelope button. If your phone is the Yealink model, press the Message button. You will be prompted for your password which will be your extension by default. You will be guided through recording your Name, Unavailable message, and Busy message. You will then be asked to enter a new password. DO NOT enter the new password as your extension number or you will be asked to rerecord your messages each time you enter your voicemail.
When receiving a voicemail you may listen to it from the phone itself. You will also receive an email notifying you that you have received a message. This message will contain a link so that you may listen to your messages online if you wish. You may also access your voicemails at https://voice.bullardisd.net/ucp/. Note: Your username and password for this portal is your extension number and voicemail password. If you wish to send a person a voicemail without calling them first, dial a * before their extension. For example, if you wished to leave a voicemail for the person with extension 1234, dial *1234.
Do Not Disturb
To toggle Do Not Disturb (DND) on and off on the Grandstream model phone, dial *76. You will hear an automated message telling you the current status of DND.
You don't have to use a special prefix to dial out, just dial the number. However for legacy reasons you can prefix the number with a 9.
