They system has finished First Time Setup widzard however some new users haven't initialized their voicemails yet. is there a option or setting under users / phones to remind user to change voicemail password when user first time login to voicemail system?
When user accesses voicemail for the first time, there is a menu option to change the default password, record a greeting, name etc.
there is no prompt to ask you to change the Voicemail user password when access to voicemail for the first time.
by default, the Voicemail password is 1234 and it's very easy to get hacked if user forgot to change it.
Once you are in Voicemail system, press Setup Option (4), followed by Preferences (3), followed by Change PIN Menu (1) to change the PIN.
It will change the PIN of other phone services also, for example Extension Mobility.
