# Verifying NaturalFax

After you install and configure the NaturalFax software, verify that the system is operational before you continue.

## Verifying the NaturalFax library

Use the Natural Access version checker utility, ctavers, to verify that the NaturalFax software can be successfully loaded. The Natural Access version checker verifies that all the Natural Access libraries defined in the Natural Access configuration file (cta.cfg) are accessible. The version checker program displays a list of the versions of all the Natural Access components.

Refer to the Sample Natural Access configuration file for more information.

To run ctavers, enter:

## Sending and receiving a fax

Use nfxsend and nfxrecv to send and receive a test fax. You can use the sample TIFF_F file, sample.tif, to verify your installation.
