Fax Troubleshooting

If you have problems sending or receiving faxes, complete the following steps:

STEP 1 Verify that your fax machine is set to a speed between 7200 and 14400.

STEP 2 Send a test fax in a controlled environment between two ATAs.

STEP 3 Determine the success rate.

STEP 4 Monitor the network and record the statistics for Jitter, Loss, and Delay.

STEP 5 If faxes fail consistently, capture a copy of the SRP configuration by downloading

the following file. You can then send this file to Technical Support.

http://<SRP_IP_Address>/admin/config.xml&xuser=admin&xpassword=<admin_password>

If you are using a web browser, choose the option to view source for the resulting

page and save this file locally.

STEP 6 Enable and capture the debug list.

NOTE You can also capture data using a sniffer trace.

STEP 7 Identify the type of fax machine connected to the device.
