HOW TO: Install and Configure Telephony Server for Client Access

This article was previously published under Q259375
Windows 2000 Server and Windows 2000 Advanced Server include a telephony server for distributed access to shared telephony devices. For example, a LAN-based server may have multiple connections to a local telephone switch or PBX. Telephony Application Programming Interface (TAPI) operations invoked by a client are forwarded over the network to the server. The server can then use a third-party call control between itself and the PBX to fulfill the client's call control requests.

How to Enable or Disable a Telephony Server

  1. Click Start, click Run, type mmc, and then press ENTER.
  2. Click Console, and then click Add/Remove Snap-in.
  3. Click Add, and then click Telephony in the list.
  4. Click Add, click Close, and then click OK.
  5. In the console tree, click the plus sign (+) next to Telephony to expand the item, and then click the server you want to manage.
  6. On the Action menu, click Properties.
  7. On the Setup tab, click to select the Enable telephony server check box to enable the server (or click to clear the check box to disable the server).

    NOTE: If the Enable telephony server check box is unavailable, you need to start the Telephony service first. To do this, use the following steps:
    1. Click Start, point to Settings, click Control Panel, and then double-click Administrative Tools.
    2. Double-click Services.
    3. Right-click Telephony in the list of services, and then click Start.
  8. After you enable the server, specify a logon account in the Account Information area.

    NOTE: The logon account you specify must be a member of the Administrators group on the server. It must also be in the same domain as the server or in a domain that has a two-way trust relationship with the domain containing the server.

How to Assign a Telephony User to a Line or Phone

  1. In the console tree of the Telephony command console, click the service provider you want to manage (for example, Unimodem 5 Service Provider).
  2. In the details pane, in the Line Name or Phone Name area, click the appropriate line or phone.
  3. On the Action menu, click Edit Users, and then click Add.
  4. In the Look in box, click the domain that contains the user.
  5. In the list, click the user, and then click Add.
NOTE: You can also start the Telephony management console in Windows 2000 Server, by clicking Start, clicking Run, typing tapimgmt.msc, and then clicking OK.

This procedure changes whether clients can use the telephony devices accessible to the server. Changes take effect the next time the computer attempts to start the TAPI service.

To manage the Telephony service, you must be a telephony administrator on the server or logged on as an administrator of the server.

How to Specify Telephony Servers on a Windows 2000 Client Computer

On the client computer, click Start, click Run, and then type the following command:
tcmsetup /c server1server2
The server1 and server2 variables represent names of one or more TAPI servers. The command replaces any previous list, so make sure you list every telephony server you want to make available to the client.

The TAPI client is installed with the Windows 2000 operating system, but you need to perform this procedure to specify servers for the client. The client must be in the same domain as the server or in a fully trusted domain.

You must log on to the client as an administrator to perform this command. If you are logged on to a computer in the Users or Power Users group, you can use the runas command to run Tcmsetup as an administrator, as shown in the following example:
runas /user:mydomain\myname "tcmsetup /c servername"
NOTE: You may have to restart the Telephony service for this change to take effect.

Before client users can dial out using the phone lines on the TAPI server, the TAPI server administrator must also assign the users to the phone lines.

Note that Telephony Server is not a modem-sharing server and it does not function as such. To share a connection for Internet access, Microsoft encourages users to use Internet Connection Sharing (ICS) in Windows 2000 Professional, or Microsoft Proxy Server 2.0 Network Address Translation (NAT) in Windows 2000 Server. You can use either of these methods to allow multiple users to use and share the same connection to the Internet simultaneously.
