pre-populate CRM form fields

Hello,

   I am working on the integration of Ms CRM 2011 and a adapter (a toolbar which enables voice telephony or multimedia interactions).

If the agent receives a call, we got automatically a pop-up window "new phone call" .

  Now we would like that when the "new phone call" pops up, the fields such as "Phone Number " " Subject" could be pre-populated according to the attached data of the call.

   Actually the configurations are made on "configuration editor", a tool provided by the developpers of the adapter. We added the options like "phonecall.phonenumber -- interaction.UserData.ANI ".  There isn't any error in the log, but the fields are never pre-populated.

   So I would like to know if anyone has some idea what might be wrong?

Thank you for your help!
