Retrieving the phone extension

[jpzc]

I would like to be able to retrieve the extension of the phone using a Meridian Communications Adapter through a serial cable to my pc using AT commands. But I cannot find an AT command that will work. The phone we are using is a Meridian 2616. Does anyone know of any AT command that will give me this info?

Using the transparent mode AT command, ATTSP!, I get data and some of it is display data. Is there any way that I can get the extension on the display and get that data?

We really don't want to us TAPI.

Thanks to anyone with any suggestions.
