Cisco CallManager configuration for Tesira using the VoIP web interface

Biamp’s VoIP-enabled products have the ability to make and receive phone calls over many different Voice-over-IP (VoIP) systems that adheres to the SIP (Session Initiation Protocol) standard. This article details the steps required to configure a Cisco CallManager VoIP system to work with Biamp's Tesira VoIP products, using the built-in web interface on the VoIP endpoint.

Please first review the requirements for using the VoIP web interface to configure a Tesira VoIP endpoint.

Cisco configuration

In this section, we'll focus on setting up the Cisco CallManager server.

MAC Address

Cisco CallManager requires the MAC address of the Tesira's VoIP port in order to add a record for the device.  You can get the VoIP MAC address of the Tesira using one of the following methods:

  • By navigating the LCD front-panel menu of the Tesira device
  • Using Tesira software:
    • Open Device Maintenance
    • Click on the "Network Settings" button. 
    • Within that window is a tab that will list all MAC addresses for a Tesira device, including the MAC addresses of each Tesira VoIP interface.

For Help reaching the device via the Tesira software See this article on device discovery.

Security Profile

The first step to setting up the CallManager system is to create a Security Profile. If your CallManager system already has an existing Security Profile that you'd like to use, you may be able to skip this step, although you should confirm that the existing Security Profile has the settings described below. Follow the steps below to create a Security Profile:TesiraCiscoSecurityProfile.jpg

  1. Go to System—>Security—>Phone Security Profile.
  2. Click the "Add New" button.
  3. Select the Phone Security Profile Type
    1. If you plan to use the Tesira for a single extension, choose Third-party SIP Device (Basic).
    2. If you plan to use the Tesira for two separate extensions, choose Third-party SIP Device (Advanced).
  4. Click the "Next" button.
  5. Enter a name and a description for the new Security Profile.
  6. Leave the Nonce Validity Time at its default value of 600.
  7. Set the Transport Type to either UDP or TCP (but not both).  Tesira's default Transport type is UDP.  Take note of the transport type used, as it will be used later as the Transport setting in the Tesira webpage.
  8. Click the checkbox to Enable Digest Authentication.
  9. Leave the SIP Phone Port at its default value of 5060 unless your particular situation requires SIP traffic to be transmitted on a different port. If this is the case, you'll need to specify this port in the Tesira endpoint card as well.
  10. Click the "Save" button.

Add a new user

Once a suitable Security Profile has been created, a new user must be created. Follow the steps below to create a new user:TesiraCiscoAddUser.jpg

  1. Go to User Management—>End User.
  2. Click the "Add New" button.
  3. Enter a user ID. Take note, as it will be used later as the Authentication Name in the Tesira webpage.
  4. The password and PIN number are not required.
  5. Enter a Last Name (this name is for internal descriptive purposes only).
  6. Enter a password in Digest Credentials. Take note, as it will be used later as the Authentication Password in the Tesira webpage.
  7. Enter the same password in “Confirm Digest Credentials”.
  8. The remaining fields on this page can be left either blank or at their default values.
  9. Click the “Save” button.

Add a new device

Once a new user has been created, a new device must be created. This device will link to the Security Profile and the user created in earlier steps. Follow the steps below to create a new device:

  1. Go to Device—>Phone.
  2. Click the “Add New” button.
  3. Select the Phone Type.
    1. If you plan to use the Tesira for a single extension, choose Third-party SIP Device (Basic).
    2. If you plan to use the Tesira card for two separate extensions, choose Third-party SIP Device (Advanced). Note that the Third-party SIP Device (Advanced) setting allows up to 8 lines, but a Tesira endpoint card uses a maximum of 2 lines. This results in a "partially registered" message from Call Manager. This is normal and not a cause for concern.
  4. Click the "Next" button.
  5. Input the MAC Address of the Tesira VoIP interface. Note that the colons should not be included in the MAC Address (see screenshot).  If you do not have the MAC address, see the MAC Address section above.
  6. The Description field will auto-populate once the MAC Address has been entered.
  7. Select the desired Device Pool in which this device should be included. Ensure that the codec used by this device pool is supported by Tesira (Tesira endpoints support the following codecs: G.722, G.711μ, G.711A, G.729AB, and G.723.1).
  8. The remaining fields under the “Device Information” heading can be left at their default values.
  9. For the Device Security Profile, choose the Security Profile created earlier.
  10. For SIP Profile, choose "Standard SIP Profile".
  11. For the Digest User, select the User created earlier.
  12. The remaining fields under the “Protocol Specific Information” and “MLPP Information” headings can be left at their default values.  If you experience problems dialing DTMF digits from the Tesira endpoint, you may need to check the “Require DTMF Reception” checkbox.
  13. Click the “Save” button.
  14. Once your information is saved, you will be brought back to the configuration page for the device you just created. The only difference will be that there is a new “Association Information” section in the top left corner. If you’re in Basic (single extension) mode, you should see one line here. If you’re in Advanced (two extensions) mode, you should see up to 8 lines here.
  15. Click on “Line [1] - Add a new DN”.
  16. Enter the directory number for this extension. Take note, as it will be used later as the "Line"  Setting in the Tesira webpage.
  17. Set both the “Maximum Number of Calls” and “Busy Trigger” fields to 6.  A Tesira endpoint can support up to 6 call appearances per line.
  18. The remaining fields on this page can be left at their default values.
  19. Click the “Save” button.
  20. If you’re setting up a 2-line configuration, click on the “Line [2] - Add a new DN” and repeat steps 16-19 above. Otherwise, the -
  21. CallManager setup is complete.

Tesira configuration 

Next, we'll focus on setting up the Tesira configuration to match the settings that were used in CallManager.

Accessing the VoIP web page

WebPage_Login.pngTo access the VoIP web page, connect a computer to the VoIP network, open a web browser, and enter the IP address of the VoIP port. If successful, a login page will be displayed.

Default username: admin

Default password: admin

If you do not see a login screen, ensure the following:

  • The Tesira device must be running firmware version 3.8 or newer.
  • The Tesira system must be running a configuration file that includes a VoIP block.
  • This Tesira system must have either HTTP or HTTPS access enabled on the VoIP port, as described here.

Network Configuration

  1. IPconfig_Webpage.pngUnder the Network window, set “VLAN” to “Enabled” if your VoIP network uses a tagged VLAN.  If the network uses an untagged VLAN or no VLAN, leave this value as disabled”.  If VLAN is enabled, enter the correct VLAN ID.
  2. Leave “DHCP” set to “Enabled” if the Tesira VoIP will obtain an IP address automatically from a DHCP server.  Otherwise, set “DHCP” to “Disabled”, and manually enter an appropriate static IP Address, Subnet Mask, and Gateway for the Tesira VoIP endpoint

To access the optional advanced network features, click the "Switch to Advanced" button.

To write the settings to the VoIP card click on "Save Changes" and then "Apply Saved Changes". After the changes have been saved, you will be brought back to the login page.

Protocol Configuration  

Take note as the Terminology between Cisco CallManager and Biamp may vary. Here is a quick rundown of different terms:

Biamp   Cisco CallManager
Line = Directory Number
Authentication Name = User ID
Authentication Password = Digest Credentials
  1. CiscoBasic_Webpage.pngNavigate to Line 1 setup on the left of the screen, then select the "SIP Config" tab.
  2. Set the "Proxy Vendor" field to "Cisco".
  3. Enter the Directory Number you used in the CallManager settings into the Line field (see “Add a New Device”, step 16).
  4. In the Display Name field, optionally enter a name for the extension for Caller ID purposes.  Note that this name may be overridden by the proxy server, and therefore may not show up as the Caller ID name.
  5. Enter the user ID you used in the CallManager settings in the Authentication Name (see “Add a New User”, step 3).
  6. Enter the Digest Credentials you used in the Call Manager settings in the Authentication Password field (see “Add a New User”, step 6).
  7. In the “Proxy Address” field, enter the IP address of the Cisco CallManager server.  If you have separate Subscriber and Publisher servers, enter the IP address of the server that will act as the active registrar for end point devices.  Also note that Tesira devices do not currently support Cisco server redundancy and will only register to a single server.  If a failover occurs the Tesira VoIP device will continuously register to the primary Cisco server and the connection will heal upon this server's return.
  8. CiscoAdv_Webpage.pngUnder the “SIP Config” tab on Line 1 Setup, ensure that “Transport” is set to the same transport type you used in the CallManager settings (see “Security Profile”, step 7). To see this setting, you will need to switch into "Advanced mode".
  9. If your network prioritizes VoIP traffic using Quality of Service (QoS), select the “Quality of Service” tab and enter the appropriate settings for your network.  Otherwise, skip this step. By default, Diffserv is the default selection on the Tesira endpoints.
  10. If you’re configuring two lines, select “Line 2 Setup” at the left of the browser at the top of the page and repeat steps 4-9.
  11. All other settings can remain at their default values in most cases. 
  12. Once all settings have been added, save the changes by clicking "Save Changes".

 

 

 

To send the changes to the Tesira VoIP interface, click "Apply Saved Changes". This will send the new settings to the VoIP interface. The VoIP interface will then briefly reboot, and start working based on the new settings.
