Yes, provided:

1. The ISDN caller is capable of using DOSBS (Data Over Speech Bearer
Service) protocol.

2. Telco doesn't break things with digital padding.

3. There is at least one modem card in the PM3. The modem isn't used
once the call is established, but it has to be there for the PM3 to
answer what appears arfirst to be an analog call. As soon as the
PM3 answers, ISDN will establish in under a second, freeing the
modem.

We are doing this. It works.
