Hi,
With asterisk their are multiple ways of working with the voice-mail application.
The nice thing is that most things that annoy you as user can be tailor made.
Here are some option that i feel are handy:
Don't ask for passwordIn the extensions.conf in the [default] context their is an extension assigned to the voicemail application.
By adding a 's' in front of the mailbox you won't be prompt for the password.
exten = 2345,1,VoiceMailMain(s${CALLERID(num)}@default)
Automatic goto next messageQuickly going through your voice-mails can be some-kind time consuming. By adding the following line to the general context of the voicemail.conf you can automaitcly skip to the next message after pressing 7 or 9.
nextaftercmd=yes
Disable the 'leave message after the tone ....' messageBy using the option 's' in de dialplan you can disable the default voicemessage.
exten=s-NOANSWER,1,Voicemail(${ARG1},su)
These parts could be default find inside the extensions.conf under the macro's: macro-stdexten and macro-stdexten-followme.
