Fax/Voice Mode Tests
The test voice port switch fax command forces a voice port into fax mode for testing. After you enter this command, you can use the show voice call or show voice call summary command to check whether the voice port is able to operate in fax mode. If no fax data is detected by the voice port, the voice port remains in fax mode for 30 seconds and then reverts automatically to voice mode.
The disable keyword ends the forced mode switch; however, the fax mode ends automatically after 30 seconds. The disable keyword is available only while the voice port is in fax mode.
To force a voice port into fax mode and return it to voice mode, use the following commands in privileged EXEC mode:
| Command | Purpose |
Step 1 |
|
|
Router# test voice port slot/subunit/port switch fax | Identifies the voice port you want to test. Enter the | |
|
| keyword fax to force the voice port into fax mode. |
Step 2 |
|
|
Router# test voice port slot/subunit/port switch | Identifies the voice port on which you want to end | |
| disable | the test. Enter the keyword disable to return the |
|
| voice port to voice mode. |
