Can someone tell me how to get a lamp on the phone to light when there are messages in the extensions mail box. I created a voice mail VPK but the lamp does not work
You shouldn’t need to allocate a button for VM as it should be already available on the extension sip settings - Voicemail *97, and the extension needs to have a valid extension line/account key with the voicemail made active on the system for the extension.
How do they know if they have a voice mail. The lamp does not light up
