How do I check my voicemail from another phone, or check another voicemail from my phone (Shoretel)?
On your new phone (silver - Shoretel), there is a button labeled "Voice Mail" on the right side of the handset. Press Voice Mail. When you hear the voice mail greeting, press the pound (#) button. You will then be asked to enter the extension for the voicemail you want to check.
This will work for checking your voice mail from someone else's phone or for checking voice mail on a second line from your own phone.
