Only phones with Basic and Enanced Dialers are eligible for Visual Voicemail.
To clear stuck voice message indicators on desk phones or OTT clients, dial **99 then press Send from the device. Afterward the system plays the following message: "Your voice message waiting indicator has been cleared."
Desk phone users can also dial *86 to access or set up Basic Voicemail.
If the voicemail greeting plays, press the # key to interrupt it.
