1 Configuring a Cisco CallManager system to work with Biamp s SVC-2 card Tesira Voice-over-IP Interface Biamp s SVC-2 card allows Biamp Tesira digital signal processors to make and receive calls over any VoIP system that adheres to the SIP (Session Initiation Protocol) standard. This document details the steps required to configure a Cisco CallManager VoIP system to work with Biamp s SVC-2 card. The steps below will work on any CallManager 8.x or 9.x version, however the screenshots in this document were taken on Callmanager version 8.5. Some screens may appear slightly different on CallManager 9. Preliminary Steps Before configuring the CallManager system, there is some information that needs to be obtained. First, note the MAC address of the SVC-2 card. To do this, first connect to the configured Tesira system using the Tesira software. Then, double-click on the VoIP Control/Status block and select the Network tab. The MAC address of the SVC-2 card is listed at the top of the page (see Figure 1 below). Note that the MAC Address will only appear here if you are connected live to the Tesira system. The second preliminary step is to verify that the CallManager system has enough licenses available. From CallManager s perspective, the SVC-2 card appears as a third party SIP endpoint. Cisco requires that a sufficient quantity of licenses be purchased from them before a third party SIP endpoint can be integrated into the CallManager system. Please contact Cisco if you are unsure of how many licenses are required for your application. Figure 1 VoIP Control/Status block dialog 1 of 6

2 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: 1. Go to System >Security >Phone Security Profile. 2. Click the "Add New" button. 3. Select the Phone Security Profile Type (see Figure 2) a. If you plan to use the SVC-2 card for a single extension, choose Third-party SIP Device (Basic). b. If you plan to use the SVC-2 card 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 (see Figure 3). 6. Leave the Nonce Validity Time at its default value of Set the Transport Type to either UDP or TCP (but not both). The setting you choose here must match the Transport setting in the SVC-2 card (see page 5, step 5), which is UDP by default. 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 SVC-2 card as well. 10. Click the "Save" button.

3 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: 1. Go to User Management >End User. 2. Click the "Add New" button. 3. Enter a user ID. This username will be used as the "Authentication User Name" in the SVC-2 card. (see Figure 4) 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. This password will be used as the Authentication Password in the SVC-2 card. 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. Figure 4 Add New User screen 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. a. If you plan to use the SVC-2 card for a single extension, choose Third-party SIP Device (Basic). b. If you plan to use the SVC-2 card for two separate extensions, choose Third-party SIP Device (Advanced). 4. Click the "Next" button. 5. Input the MAC Address of the SVC-2 card. Note that the colons should not be included in the MAC Address. (see Figure 5) 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 the SVC-2 card (the SVC-2 card supports 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. 3 of 6 Figure 5 Top section of Add New Device screen

4 9. For the Device Security Profile, choose the Security Profile created earlier. (see Figure 6) 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 SVC-2 card, 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 an 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. (see Figure 7) 15. Click on Line [1] - Add a new DN. 16. Enter the directory number for this extension. This directory number will be used as the SIP User Name in the SVC-2 card settings. (see Figure 8) 17. Set both the Maximum Number of Calls and Busy Trigger fields to 6. The SVC-2 card 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 above. Otherwise, the CallManager setup is complete.

5 Configure SVC-2 Card Finally, after all CallManager settings have been entered, follow the steps below to set up the SVC-2 card: 1. Open the Tesira software, and open the.dap file for your project. Do not connect to the Tesira system yet, because the information below cannot be entered while you are connected to the Tesira system. 2. Right-click on the VoIP Control/Status block and select Properties. At the top of the Properties Sheet, select the DSP Properties tab. 3. Under the Network General category in the Properties Sheet, 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. 4. Under the Network General category in the Properties Sheet, leave DHCP set to Enabled if the SVC-2 card 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 SVC-2 card. 5. Under the Protocol SIP category in the Properties Sheet, ensure that Transport is set to the same transport type you used in the CallManager settings (see Security Profile, page 2, step 7). 6. Under the General category in the Properties Sheet, click on the symbol next to Line Properties. This will open the VoIP Line Properties window (see Figure 9). 7. Select the Protocol tab. 8. In the SIP User Name field, enter the Directory Number you used in the CallManager settings (see Add a New Device, page 4, step 16). 9. In the SIP 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. Figure 9 VoIP Control/Status block Line Properties dialog 10. In the Authentication User Name field, enter the user ID you used in the CallManager settings (see Add a New User, page 3, step 3). 11. In the Authentication Password field, enter the Digest Credentials you used in the Call Manager settings (see Add a New User, page 3, step 6). 12. Select Cisco as the Proxy Vendor. 13. 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 Publisher server. 14. 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, only the Diffserv attributes are available. If you prefer specifying QoS using TOS, select TOS as the QoS mode in the Properties Sheet and return to this page. 15. If you re configuring two lines, select Line 2 at the top of the page and repeat steps All other settings can remain at their default values in most cases. 5 of 6

If you have a Dialer block associated with your SVC-2 card, you can see status messages returned from the SVC-2 card at the bottom of the Dialer block s control dialog (see Figure 10). See below for a description of some of the possible status messages and their meanings: Blank If the status field is blank, then the SVC-2 card is successfully registered and ready to make a call. (This is assuming you are connected live to the Tesira system, as the status window will also be blank when Tesira software is offline). Network is Down A physical network connection has not been sensed on the SVC-2 card s Ethernet port. Network is Up A physical network connection has been sensed on the SVC-2 card s Ethernet port, however communication with the proxy server has not yet been established. DHCP In Progress The SVC-2 card has been set to obtain an IP address via DHCP, and is currently requesting an address from the DHCP server. Proxy Not Configured A valid IP address or hostname was not supplied in the VoIP Line Properties page (see page 5, step 13). SIP User Not Configured A SIP User was not supplied in the VoIP Line Properties page (see page 5, step 8). Auth User/Password Not Configured The Authorization Username or Password was not supplied in the VoIP Line Properties page (see page 5, steps 10 and 11). Registering The SVC-2 card is attempting to contact the proxy server. If this message never goes away, the SVC-2 card may not be able to communicate with the proxy server. Double-check network settings of the SVC-2 card and the Proxy Address. Authentication Failed The SVC-2 card has attempted to register with the proxy server but received an error message in response to its registration attempt. Double-check that the Authentication User Name and Password match what was entered into CallManager, and that CallManager has a sufficient number of licenses available.
