HOWTO: Configure a Cisco SPA122 Analog Telephone Adapter for Fax Relay

ID: ZTN1848

This Zetafax technical note applies to:

  • Zetafax 2012 or later
  • Fax Relay addon
  • Cisco SPA122 Analog Telephone Adapter

Summary

This technical note provides information on how to configure the Cisco SPA122 analog telephone adaptor (ATA) for use with the Zetafax Fax Relay addon.

More information

The Cisco SPA122 ATA can be used to connect your existing physical fax machines to your Zetafax server. This will free up lines, saving on line rental, as well as integrating your existing fax machines into a centrally managed infrastructure. 

The simplest way to configure the unit is using a web browser on a computer which is directly connected to the device.  The instructions below explain how to connect the unit to your computer and configure the required settings.

Step 1: Reset to factory default settings

If the device has been used previously with another application, or the state of the device is unknown, then we recommend that you reset to factory default settings before configuring it for use with Zetafax.

The simplest way to do this is by using a connected fax device (if it includes a speaker, and supports going off-hook then entering numbers individually from the keypad), or an analog phone handset connected to the unit.  To use a fax device or phone, lift the handset or go off-hook, then enter the following commands from the keypad:

****

Enable interactive voice system (IVR)

Reset to factory default settings

Step 2: Connecting the device to a configuration computer

Configure your computer to obtain an IP address automatically using DHCP – client computers which connect to a company network will usually be configured with this option already.

The device comes with two network ports, labelled “Internet” and “Ethernet”.  Connect it to your desktop computer or laptop with a network cable using the port labelled Ethernet on the rear of the Cisco device.

Next, run Internet Explorer on your computer and adjust the browser settings (if necessary) to disable use of a proxy server. 

Web browsers used on computers within a company network are typically configured to use a proxy server, which is a shared server used to access the Internet.  This must be disabled to connect directly to the ATA unit.  The setting is typically found in “Internet Settings > LAN settings” or similar location in the browser configuration menus.

The configuration web site is designed for use with Internet Explorer, and may not display correctly in some other browsers.

Now browse to address  http://192.168.15.1  to display the login page for the Cisco configuration utility:

Log into the configuration utility.  The default settings are:

        Username:        admin
        Password:        admin

Step 3: Configuring the settings for Line 1

On the Voice settings tab, Choose Line 1 from the list on the left of the display to show the settings for the first phone port.

Configure the settings as follows:

  • In the Network Settings section, set the following options:
  • Network Jitter Level

    VERY HIGH

    Jitter Buffer Adjustment

    NO

  • In the Proxy and Registration section, set the following options:
  • Proxy

    ZetafaxServerIPAddress:5060
    (eg  “192.168.0.74:5060”)

    Register

    NO

    Make Call Without Reg

    YES

    Ans Call Without Reg

    YES

  • In the Subscriber Information section, set the following options:
  • User ID

    Zetafax

  • In the Audio Configuration section, set the following options:
  • Preferred Codec

    Second Preferred Codec

    G711u

    G711a

    Use Pref Codec Only

    YES

    Silence Supp Enable

    NO

    Echo Canc Enable

    YES

    FAX Passthru Method

    REINVITE

    Fax Disable ECAN

    YES

    Fax Enable T38

    YES

  • In the Dial Plan section, enter the following text in the Dial Plan field:
  • (xxxx | < :*> xxxx*,xxxxxx. | < :*DeviceID*> xxxxxx.)

            replacing DeviceID with a unique Fax Relay identification number for the device (eg “501”). 

    The Device ID is used on the Zetafax Server to identify the fax machine used for submitting a fax, so that the result page is printed on the correct device.  Each ATA device port should be allocated a unique Device ID.  We recommend that Device IDs are 3 digits long, starting from 501.

    The dial plan text must be entered exactly as given, including the round brackets at the start and end of the string and all other punctuation, and without any additional spaces except where shown.  The dial plan text given configures the unit to enable users to send a fax in 3 ways as described in the Fax Relay user documentation:

    a)        Entering just a 4 digit user identifier as the fax number (eg “1234”), to send the fax to an internal user – the dial string is passed to Zetafax unchanged

    b)        Entering their own 4 digit user identifier followed by star then an external fax number (eg “1234*2223334444”), to send the fax from their own Zetafax account – the dial string is passed to Zetafax with an additional star added to the start.

    c)        Entering just an external fax number of at least 6 digits (eg “2223334444”) to send the fax using a shared account (anonymous use) – the dial string is passed to Zetafax with a star then the Device ID then another star added to the start.  The Device ID is used to identify the shared account to use, and the Zetafax Server prints a transmission result page on the same device (for multi-function fax devices) or a nearby printer when the fax completes.

    The dial plan given can be adapted for systems where the direct dial identifier for each user is not 4 digits by replacing the string “xxxx” with the required number of digits.  Other more advanced dial plan options are available – please consult the Cisco documentation or contact Technical Support to discuss other options if needed.

Now press the Submit button (at the bottom of the settings screen) to save the new settings.

Step 4: Configuring the settings for Line 2

We recommend configuring the settings for the second line to simplify future expansion, even if the unit is only expected to be used with a single fax device.

On the Voice settings tab, choose Line 2 from the list on the left of the display to show the settings for the second phone connection, repeat the settings as detailed above but using the next Device ID (eg “502”), then press Submit to save the settings for line 2.

** OPTIONAL**  Step 5: Enabling configuration over the LAN

In most installations there is no need to use the configuration tool after initial configuration of the ATA device.  However in some cases it may be useful to allow the device to be configured over the LAN – for example in test systems where the ATA unit is required to connect to multiple Zetafax Servers, or to assist in troubleshooting configuration issues.

To enable configuration over the LAN, select the Administration tab, then change the following settings:

  • Choose Management > User List in the left hand menu, edit the user named “admin” by clicking on the pencil icon then change the password.

The Cisco SPA122 ATA does not allow you to enable remote access unless you first change from the default administrator password.  Note that this change also affects using the web configuration utility from a directly connected computer – if you forget the login password then it will be necessary to reset the device to factory default settings then reconfigure the unit

·                In Management > Web Access Management, change the following settings then press Submit:

Web Access section

Admin Access

ENABLED


Remote Access section

Remote Management

ENABLED

Step 6: Connecting the unit to the LAN and fax device

The device is now configured.  You can now disconnect the device from your computer and connect it to the company network.

The device comes with two network ports, labelled Internet and Ethernet.  Connect it to your company network using the Internet port.

*** WARNING ***
Do NOT connect the unit to the corporate network using the port labelled “Ethernet”, as this port will act as a DHCP server which could interfere with other computers on the network.  We recommend putting tape over the Ethernet port to protect against inadvertent use.

Next, connect the phone line from the fax device (multifunction device or fax machine) to the Phone 1 socket on the ATA unit.

Step 7: Testing the configuration

Ensure that the Zetafax Server has been configured for Fax Relay, that a Zetafax user account has been created for use with the device, and that a routing rule has been created to associate the allocated Device ID with that user account.

To test the device has been configured correctly, perform the following checks.

  • Check that the power LED is lit, and that the Internet connection LED is flashing to show network connectivity.
  • Send a fax from the fax device, entering just the number.  Check that the Line 1 LED lights, and that the fax is sent by the fax device (to the Zetafax Server) successfully.  Check the Zetafax Server monitor program – you should have messages showing that the fax was received from the fax device, then queued and sent out again using the specified user for that device.  Provided the Zetafax Server has been configured correctly then a status report should be printed on the device or a nearby printer.
  • If you have a direct dial user ID, then send a fax from the fax device to yourself by entering just your 4 digit user ID as the fax number.  Check the Zetafax Server monitor program – you should see the received fax being routed to your Zetafax account, and the fax should be delivered to your Zetafax Inbox or email just as other received faxes.
  • Finally if you have a direct dial user ID, then send a fax to an external number using your own Zetafax account by entering the fax number in the following format:

                             userID * faxnumber

Check the Zetafax Server monitor program – you should see the fax being sent using your Zetafax account, and see the fax in your Zetafax user account.

Once the testing is completed successfully, then the device is ready for use.

** OPTIONAL**  Step 8: Determining the IP address of the unit

If you enabled configuration over the LAN (optional step above), then you will need to determine the IP address of the unit on your network.  This can be found using the connected fax device (if it includes a speaker, and supports going off-hook then entering numbers individually from the keypad), or an analog phone handset connected to the unit.  To use the fax device or phone, lift the handset or go off-hook, then enter the following commands from the keypad:

Command

Description

****

Enable interactive voice system (IVR)

110#

Announce WAN (Internet port) IP address


Alternatively you can determine the IP address using a computer connected directly to the Ethernet port as above, by running the Cisco configuration utility then choosing Status  >   Interface  Information.
