I'm using a Zoom 3025C PCI modem.
Running WinXP SP2.
IVM 3.02 (problem occurs with version 2.43 as well).
When a call is answered, the command 'at+vls=1' fails (attempting to select the source/destination as 'off hook, connected modem line').
A snippet of the modem log is:
09-03-2005 10:27:23.615 - Answering the call.

Does anyone have any ideas?
