# A typical fax application

The following illustration shows the functions involved in a typical application that can transmit or receive faxes. NaturalFax invokes functions for transmitting and receiving a fax when a call is in the connected state. The document queue can be destroyed as soon as the fax session is complete, or after the call is disconnected.

Note: If you are using QX 2000 boards, use QDIMGR instead of ADIMGR.
