IP Phone LCD Display


#1

Is it possible to use the LCD display of a phone as well as the extra buttons that correspond to the screen with an Asterisk system?

For example: On a meredian system with nortel phones one can fast forward, rewind or stop a message being played on their voicemail. While in a message the LCD displays the message date and time, too.

My question is for new IP phones and not the phones mentioned above in the example.

If this is done, where can I read details about how to do it?

Thanks!

This can be done with something called ADSI, (if you phone supports it) have a look at:

for more information

That’s great. Thanks for the info. However, I think I’m a bit confused as to what the LCD is for on all the other IP phones that supposedly work well with Asterisk but don’t support ADSI. Are they for the phone interface or is Asterisk communicating some other way to the phone?

Most of them are just for the phone interface, some can also accept incoming messages. Some are also capable of talking to a callmanager or so and do some interactive things with that.

But the use with asterisk for interactive things is quite limited.

Is it possible to use the extra buttons on an IP phone to fast forward and rewind a message while displaying the date and time the message was left? If so, how would one go about that?
