1. Open the Express Modem control panel and verify the Express Modem is turned on.
2. From the General Settings pop-up menu, choose "Advanced Options." Make sure that unknown calls are selected to be transferred to the Voice application.
3. Open AppleFax and verify that the Receive Faxes option is in the ON position.
4. Open Megaphone and choose Preferences from the File menu.
5. From the Topics pop-up menu, choose Mailboxes. Ensure that "Allow Megaphone Voice Messaging" is enabled.
6. From the Topics pop-up menu, choose Incoming Calls. Ensure that "Come to Front When Ringing" is chosen.
This should suffice to allow the computer to automatically arbitrate between fax and voice calls.
Note that Megaphone must always be open for this feature to work.
If the above steps did not resolve your issue, you may have a software conflict. Please review the Tech Info Library articles listed below. They provide general guidance on how to troubleshoot extension conflicts.
Note that certain types of third-party performance enhancement utilities which modify the system at a low level can modify system performance enough that some features may not work correctly.
