As a fully managed device on the Webex Calling platform, the VG420/VG400 ATA offers:

  • A higher capacity 8-port option from the standard 2-port device, for Webex Calling customers

  • A direct migration path for UCM customers moving to Webex Calling.

  • Use for legacy PBXs that don't work with SIP trunking.

Hardware specifications

The Cisco VG420 Voice Gateway supports the following interfaces:

  • 2-Gigabit Ethernet (GE) interfaces, one for LAN and the other for configuration

  • RJ45 Console Port

  • FXS Ports

The Cisco VG420 Voice Gateway has these components:

  • Micro USB Console Port
  • FXO Ports
  • Network Interface Module (NIM)

The Cisco VG400 Voice Gateway has these components:

  • Eight RJ11 FXS ports for analog station devices

  • FXO ports aren’t supported on any VG400 models when connected to the Webex Calling platform.

Add an ATA device in Control Hub

Before you begin

  • Add the VG400 as a device in the Control Hub and create the workspace at the same time.

  • When adding an ATA, configure all network settings before activating the device.


     

    Configure network settings before activating the device in Control Hub. After you activate the device, you can't access VG through the Web GUI or SSH. This is because you configured the device in Control Hub and have limited access. You can’t configure network settings such as VLAN, IP address, and subnet mask.

Use the same steps to add a VG420/VG400device.

Configure the ATA device for users and workspaces

Before you begin

Add VG420/VG400 to a workspace to use for fax and overhead paging service.

Configure the ports on the VG400 ATA device to a user within Control Hub

1

From the customer view in https://admin.webex.com, go to Users.

2

Select the user to modify and scroll to Devices.

3

Select the device that you would like to add or modify.

4

Under Users on this Device, click Configure Ports.

5

To add a shared port configuration, click the + icon.

6

Enter the name or phone number and select from the options displayed.

7

Click Save.


 

You see workspaces without devices, user lines, and empty workspaces in the lookup.

If the device requires T.38 fax compression, check the box in the T.38 column under Customized Behaviors. Else you can override the user-level compression option and then click Save.

To assign a number to a port, create an empty workspace and assign a number to the workspace, then add it to the VG420/VG400.

Onboard the VG420/VG400 ATA for Webex Calling

Under certain circumstances, you may need to manually reconfigure the Cisco VG420/VG400 ATA for it to connect to the Webex Calling platform.

Before you begin

Make sure you have the following equipment:

  • A computer with an Ethernet interface

  • An Ethernet cable to connect to your network, and another to connect to your PC.

  • An analog phone, butt set, or other device along with an RJ-11 phone cable to test the analog ports.

  • Uninterruptible power supply (UPS) to provide backup power

After you onboard the ATA to Control Hub, any prior configuration settings on the voice gateway are overridden, including the administrator password. Also, the device is usable only with Webex Calling.

To use the device on any network other than the Webex Calling, reset the device to the Cisco factory default configuration.


 

The firmware supported for a VG420/VG400 ATA to connect with the Webex platform is:

VG400: vg400-universalk9.17.06.03a.SPA.bin

VG420: vg420-universalk9.17.06.03a.SPA.bin

Manually reconfigure the VG420/VG400 ATA

Section A: Log in to the VG420/VG400 through Web GUI

  1. Connect a computer to the ethernet port labeled ‘GE 0/0/1’ on the VG420/VG400 with an Ethernet cable.

    • The ‘GE 0/0/1’ port is the management port of VG. Its default IP address is 192.168.253.253.

    • The computer should get the IP address 192.168.253.254 automatically from DHCP from the VG420/VG400.

  2. From the computer, browse to the Web GUI of the VG420/VG400 using http://192.168.253.253. Login with default username cisco and password cisco2. If the Webex supported firmware isn’t installed on VG400/VG420 go to

    Section F. Convert an Existing Customer Owned Non-Webex VG420/VG400 to Work with the Webex Platform

Section B: Reset the VG420/VG400 to Factory Defaults

  1. From the VG420/VG400 web GUI, go to Administration > Reload.

  2. Select the Reset to Factory Default and Reload and click Apply button to reset the VG420/VG400 to factory default.

Section C: Verify and Configure the VG420/VG400 for Boot Parameters (Optional)

  1. From the VG420/VG400 web GUI, go to Administration > Command Line Interface page.

  2. Select the Exec mode, input command show version, then click the Run Command button to check the boot image and register setting.

    In the output of show version command, the line starting with “System image file” shows the current boot image. Make sure you configure the Cisco Webex approved image. If not, select Configure mode, run the command boot system flash <boot image name> to set boot image.

    Example: The command boot system flash:vg400-universalk9.17.06.03a.SPA.bin sets boot image to vg400-universalk9.17.06.03a.SPA.bin

    The command boot systemboot system flash:vg420-universalk9.17.06.03a.SPA.bin sets boot image to vg400-universalk9.17.06.03a.SPA.bin

  3. The last line of the output starting with “Configuration register” shows the register setting. Make sure the value 0x2102 is configured here. If not, select Configure mode and run a command config-register 0x2102 to set the value.

  4. If Register configuration gets changed at Step 2, select Exec mode and run the command write memory to save the changes.

  5. If the boot image configuration gets changed at Step 2, go to Administration > Reload page, select the Save Reconfiguration and Reload option and click the Apply button to reboot the VG400 with the new image. It takes the VG420/VG400 about ten minutes to bootup.

Section D: Configure VG420/VG400 for Webex License Report (Optional)

  1. From the VG420/VG400 web GUI, go to Administration > Command Line Interface page.

  2. Select Configure mode and input the following commands to set smart license reporting parameters:

    license smart transport smart

    license smart url default

  3. Select Exec mode and run the following commands to trigger smart license reporting:

    — license smart trust idtoken <token> local force

    — license smart sync local

    You can find the token at Smart Software Manager from the https://software.cisco.com/ website with valid user account.

Section E: Configure VG420/VG400 for Webex


 

Make sure to perform the procedures in sections A, B, C, and D before starting this step.

  1. From the VG420/VG400 web GUI, go to Administration > Command Line Interface page.

  2. Select Configure mode and input the following commands to set the local SRTP port and Webex Device Management URL:

    — voice service voip

    — rtp-port range 19560 19660

    — wxc-dm-url<Device Management URL>

    The valid setting for <Device Management URL>:

    U.S.

    https://cisco.broadcloud.com.au

    CA

    https://cisco-ca.bcld.webex.com

    JP

    https://cisco-jp.bcld.webex.com

    For example, use the wxc-dm-url command https://cisco.sipflash.com for VG420/VG400 devices installed in the U.S. region.

  3. Click Run Command.

  4. Write down the VG420/VG400’s MAC address shown at the output screen after running the commands.

  5. Add the VG420/ MAC address in Control Hub.

  6. Connect ‘GE 0/0/0’ port on VG400 to internet through DHCP.

Wait about five minutes after step 6. The VG420/VG400 is configured and ready for use with the Cisco Webex network.

Section F. Convert an Existing Customer Owned Non-Webex VG420/VG400 to Work with the Webex Platform

  1. Upgrade the VG420/VG400 to the Webex approved image (example: vg400-universalk9.17.06.03a.SPA.bin).

  2. From VG420/VG400’s console port, run the below commands to add the Webex Calling license:

    conf t

    voice service pots

    webex-calling license

    end

  3. From the VG420/VG400’s console port, run the below commands to add uck9 and securityk9 licenses:

    conf t

    license boot level uck9

    license boot level securityk9

    end

  4. Run the write memory command to ensure license boot take effect on the next boot.

  5. Run the following commands to erase all existing config and reboot the VG400:

    write erase

    reload

  6. After the VG420/VG400 boots up, follow sections A, B, C, D, and E to configure the VG420/VG400 device.

Section G: Troubleshooting

If the device doesn’t come back or there are issues, perform these steps:

  1. Verify that the device MAC address is correct in Control Hub.

  2. Verify that the device MAC address is assigned to a user/phone in Control Hub.

If the device still experiences issues, contact your technical support team for assistance.
