Avaya CS1000 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 an Avaya Communication Server (CS1000) 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.

Avaya creates and maintains application notes for certified products manufactured by Avaya's DevConnect Technology Partners. Avaya's full application note for configuring an Avaya SES system to use Tesira VoIP endpoints can be downloaded from this link. Information specific to creating the endpoint is below.

Avaya Configuration

Configure Avaya CS 1000

1. Enabling SIP Line Service

On the EM page, navigate to Customers on the left column menu; select the customer number to be enabled with SIP Line Service.

  • Enable SIP Line Service by clicking on the SIP Line Service check box.
  • Enter the prefix number in the User agent DN prefix text box as shown

2. Create SIP Line Telephony Node

On the EM page, navigate to menu System, IP Network, Nodes: Servers, Media Cards. Click Add to add a new SIP Line Node to the IP Telephony Nodes. The new IP Telephony Node page appears as shown to the right Enter the information as shown below:

  • Node ID: e.g., 512. This is the node ID of SIP Line server.
  • Call Server IP Address: e.g.
  • Node IP Address: e.g. This is the SIP Proxy IP address that SIP endpoint uses to register to.
  • Subnet Mask:
  • Embedded LAN (ELAN) Gateway IP Address: e.g.
  • Embedded LAN (ELAN) Subnet Mask:
  • Check SIP Line check box to enable SIP Line for this Node.  

Once that is completed click "Next"



3. Adding a Server to the Node

New IP Telephony Node with Node ID, will appear as shown:

  • Click Select to Add drop-down menu list to select the desired server to add to the node.
  • Click Add button
  • Select the check box next to the newly added server, and click Make Leader (not shown).

Once that is complete click "Next"


4. Configuring SIP Domain/Gateway

  • Enter SIP Line domain name in SIP Domain name text box, e.g.,
  • Note: SIP domain name can be either a domain name or IP address, in this sample the SIP domain name is presented.
  • Check the Enable gateway service on this node option for SIP Line Gateway Application.

Scroll down to the Branch / GR Office Settings section under SIP Line Gateway Service:

  • Select MO from the SLG Role list.
  • From the SLG Mode list, select S1/S2 (SIP Proxy Server 1 and Server 2).
  • Take note of MO SLG trasport as that will be configured on the endpoint.  Tesira supports UDP, TCP and TLS with UDP as the default.

Once that is Complete Click "Next" and then click "Transfer Now"


Select the SIP Line server associated with changes and then click on the Start Sync button to transfer the configuration files to the selected servers.


Note: The first time a new Telephony Node is added and transferred to the call server, the SIP Line services need to be restarted. To restart the SIP Line services, log in as administrator to the command line interface of the SIP Line server and issue command: "appstart restart."

5. Creating a Virtual Trunk Zone

On the Element Manager (EM) page, navigate to menu System, IP Network, then  Zones. The Zones page appears on the right.

On this page select Bandwidth Zones link.

On the Bandwidth Zones page  click on the Add button, the Zone Basic Property and Bandwidth Management page appears as shown.

Enter a zone number in the Zone Number (Zone) field. In the Zone Intent (ZBRN) drop-down menu select VTRK (VTRK).Leave other fields at default values and click on the Save button to complete adding the Zone.


Note: Repeat the step above to create another zone for the SIP Line phone; however remember to select MO (MO), instead of VTRK in the field Zone Intent.


6. Create SIP Line Phones

To create a SIP Line phone on the Call Server, log in as administrator and use overlay command LD 20 as shown to the right.


The bold fields must be properly inputted as they are configured on the Call server, for other fields press to leave it at default values.

NDID 512 ==> SSIP Line Node ID configured in Step 2

ZONE ==> Zone ID for SIP Line was configured in Step 5

HOT U ==> The prefix was configured in Step 1




Once you have entered this information we can move on to configure the Tesira VoIP endpoint


Tesira Configuration

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

  1. CS1000BasicView.pngNavigate to "Line 1 Setup" at the Left side of the browser window and Make sure you are looking at "SIP Config".
  2. Set Proxy Vendor to Avaya CS 1000.
  3. In the Extension field fill in the SIPU field. (see "Configure Avaya CS 1000", step 6)
  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. In the Authentication User Name (Extension) fill in the SIPU field (see "Configure Avaya CS 1000", step 6)
  6. In the Password field fill in the SCPW field.(see "Configure Avaya CS 1000", step 6)
  7. In the SIP Proxy Address Enter the IP address of CS 1000 SIP line server. (see "Configure Avaya Cs 1000", step 2)
  8. In the SIP proxy Port Field Verify that the port is 5060, 5061, or change it as needed. (see "Configure Avaya CS 1000", step 4)
  9. 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 4-10.
  10. For more advanced features click on "Switch to Advanced".


  1. CS1000AdvancedView.pngEnsure that “Transport” is set to the same transport type that is used on your network, UDP, TCP, or TLS. UDP is the default setting. (see "Configure Avaya CS 1000", step 4)
  2. 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.
  3. All other settings can remain at their default values in most cases. 
  4. 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.
