Once your information is saved, you will be brought back to the configuration page for the device you just created.If you experience problems dialing DTMF digits from the Tesira endpoint, you may need to check the “Require DTMF Reception” checkbox.
The remaining fields under the “Protocol Specific Information” and “MLPP Information” headings can be left at their default values. For the Digest User, select the User created earlier. For SIP Profile, choose "Standard SIP Profile". For the Device Security Profile, choose the Security Profile created earlier. The remaining fields under the “Device Information” heading can be left at their default values. 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). Select the desired Device Pool in which this device should be included. The Description field will auto-populate once the MAC Address has been entered. If you do not have the MAC address, see the MAC Address section above. Note that the colons should not be included in the MAC Address (see screenshot). Input the MAC Address of the Tesira VoIP interface. This is normal and not a cause for concern. This results in a "partially registered" message from Call Manager. 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. If you plan to use the Tesira card for two separate extensions, choose Third-party SIP Device (Advanced). Follow the steps below to create a new device: This device will link to the Security Profile and the user created in earlier steps. Once a new user has been created, a new device must be created. If this is the case, you'll need to specify this port in the Tesira endpoint card as well. 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. Click the checkbox to Enable Digest Authentication. Take note of the transport type used, as it will be used later as the Transport setting in the Tesira webpage. Set the Transport Type to either UDP or TCP (but not both). Leave the Nonce Validity Time at its default value of 600. 
Enter a name and a description for the new Security Profile.If you plan to use the Tesira for two separate extensions, choose Third-party SIP Device (Advanced).If you plan to use the Tesira for a single extension, choose Third-party SIP Device (Basic).Go to System->Security->Phone Security Profile.Follow the steps below 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. The first step to setting up the CallManager system is to create a Security Profile.
