Sportster Flash doesn't detect caller ID

[bekdik]

I've dug out an old USR Sportster that i want to use as a telephone answer machine. It works fine apart fom not detecting the CID. Hopefully there is an AT command option which can make it work.

My DECT phone displays CID, so everything on sems to be set up OK on Telkom side.

Any suggestions as to how to make it work?

PS. I have tried two of these modems with the same results, so I'm guessing a setting.
