I have a Partner ASA/DXD PC Card R.3. Is this a one time use card?
It is a Automatic System Answer / Direct Extension Dial card.
And you can use it in any ACS release 2.0 and higher.
It is not an upgrade grade if that is your question.
It needs to be in the ACS card slot to enable those features just like a Partner Voice Mail card. It doesn't load any software.
