Telephony Interface Manager Connector (TIMC) is the software component that allows Speech Server to communicate with a Telephony Interface Manager (TIM), which drives the interface with third-party telephony boards. TIMC is a type of SIP peer and is added to the Speech Server Administrator console in the same manner as other SIP peers. However, TIMC requires additional configuration information to operate properly with Speech Server.

Note

To add a TIMC SIP peer, the TIMC software must be installed on the computer running TIM. For more information, see How to: Install the TIMC.

When you add TIMC as a SIP peer, you must add it as a trusted SIP peer in the applicable deployment group to begin communicating with computers running Speech Server. For more information, see How to: Add or Remove a Trusted SIP Peer.

Adding TIMC as a SIP Peer

To add TIMC as a SIP peer

  1. Open the Speech Server Administrator console.

    For more information, see How to: Start the Speech Server Administrator Console.

  2. In the console tree, right-click SIP Peers, point to New, and then click SIP Peer.

  3. In the Type box, select TIMC.

  4. In the Name box, type the name you want to give the SIP peer in the Speech Server Administrator console.

  5. In the Address box, type the fully qualified domain name (FQDN) or IP address of the computer running TIMC.

    Note

    Do not begin the last name element of the SIP peer address with a number. For example, 1SIP is not an acceptable address. However, 1SIP.mydomain.com is acceptable.

  6. In the Use default ports box, use the default selections (7423 for TCP and 7424 for TLS) or clear the setting and type the TCP and TLS ports on which TIMC listens for connections from Speech Server.

  7. Click Enable Mutual TLS if you intend to use Mutual Transport Layer Security (TLS) for SIP communications with TIMC. Mutual TLS uses digital certificates, which improves the security of the transmissions between TIMC and Speech Server.

    Note

    If you choose Enable Mutual TLS, you must select a certificate for each computer running Speech Server and for the computer running TIMC. For more information about selecting a certificate for the computer running Speech Server, see How to: Set Up a Certificate for Secure SIP Peer Communication. To select a certificate for the computer running TIMC, continue following the steps in this procedure and choose Authenticate using mutual TLS when you reach the appropriate step.

  8. Click OK.

  9. Under MSS Servers, click Add.

  10. In the MSS Servers box, select the computer running Speech Server to which TIMC can send and receive calls.

  11. To specify the listening port on the computer running Speech Server, complete one of the following steps:

    • Select the Use standard port check box to use the default listening port on the computer running Speech Server.
    • Clear the Use standard port check box, and then type the port number in the Port box on the computer running Speech Server to send and receive SIP messages from TIMC.
      If you choose this setting, you must make a coordinating change to the listening port setting on the computer running Speech Server. For more information, see How to: Configure the Listening Ports for SIP Peer Communication.

  12. To specify security settings, complete one of the following steps:

    • Select the Authenticate using mutual TLS check box.
      If you choose this setting, you must specify a certificate to use for authenticating the computer running TIMC to the computer running Speech Server. If you cleared the Use standard port check box, you also need to specify the port on which Speech Server listens for TLS connections in the Port box.
    • Clear the Authenticate using mutual TLS check box.
      Choose this setting if you do not need a secure connection. For example, use this setting if TIMC is running on the same computer as Speech Server.

  13. Click OK.

  14. If you selected the Authenticate using mutual TLS check box, click Select Certificate.

  15. In the Select Certificate dialog box, select a certificate to use for authenticating the computer running TIMC, and then click OK.

  16. Click OK.

    Note

    When you add a SIP peer, Speech Server attempts to resolve the address and establish communications with it. If it is unable to resolve the address, you can correct the address or, if you know the problem is with the SIP peer or the connectivity, add the SIP peer.

    Note

    You can also add, remove, and configure TIMC through Windows Management Instrumentation (WMI) scripts.
