Question : display a message on a cisco 7960 phone

We have a Call Manager 4.3 server and Unity Voice Mail server.  I was wondering 2 things:

Can you administratively display a text message on the Cisco Ip phones from the server?

Can you send a bulk voicemail to all or some voicemail boxes on the unity server.

If so, how is this done?

Thanks!

for unity you can use public distribution lists to send a bulk messages just create a new one then add the subscriber that you want after that you can use this distribution list to send a messages.

for text messages it is simple just create a TXT file and put it  in a web server after that point the phone to this file. or you can send a file to the phone using execute command.
