Cisco TAPI Service Provider Installation and Configuration
The Cisco Telephony Application Programming Interface (TAPI) solution allows you to install multiple Cisco TAPI Service Providers (TSPs) on the same machine. This configuration allows TAPI applications to increase the number of lines that can be supported and to increase the amount of call traffic. Configure each Cisco TSP with a different username and password that is administered in the Cisco CallManager Directory. Configure each user in the Directory, so that no two users are associated to the same device. TSPs in the multiple TSP system do not communicate with each other and create a separate computer telephony integration (CTI) connection to the Cisco CallManager.
Note 
If you have upgraded to Cisco CallManager 3.1, you must upgrade the TAPI client software on any application server or client workstation on which TAPI applications are installed. If you do not upgrade the TAPI client, your application will fail to initialize. If you need to upgrade, download the appropriate client from the Cisco CallManager Administration as described in the "Installing the Cisco TSP" section.
The upgraded TAPI client software does not work with older releases of Cisco CallManager.
The following sections outline the installation of the Cisco TSP and describe some of the issues you need to be aware of after installation:

Installing the Cisco TSP
Install the Cisco TSP software either directly from the Cisco CallManager CD-ROM or from Cisco CallManager Administration. For information on installing plugins from the Cisco CallManager, see the "Installing Plugins" section on page 46-1.
To install the Cisco TSP from the Cisco CallManager CD-ROM, perform the following steps.
Note If you install TSP 3.1 on a system that contains a previous version of TSP, the installation program deletes the old version and installs TSP 3.1. The installation wizard varies depending on whether you have a previous version of TSP installed.
Note Installing multiple TSPs installs multiple CiscoTSPXXX.tsp and CiscoTUISPXXX.dll files in the same Windows system directory.
Procedure
Step 1 Insert the Cisco CallManager CD-ROM.
Step 2 Double-click My Computer.
Step 3 Double-click the CD-ROM drive.
Step 4 Double-click the Installs folder.
Step 5 Double-click Cisco TSP.exe.
Step 6 Follow the online instructions.
Next Steps
You should install Cisco wave driver if you plan to use first-party call control. (Do this even if you are performing your own media termination.) For more information, see the "Installing the Wave Driver" section.
Activating the Cisco TSP
You can install up to 10 TSPs on a computer. Use the following procedure to activate each of these TSPs. When you install a Cisco TSP, you add it to the set of active TAPI service providers.

Table 47-3 contains a list of the Wave tab fields that must be set and their descriptions.
Table 47-3 Wave Tab Configuration Fields
Field

Description
|
Automated Voice Calls
|
The number of Cisco wave devices you are using determines the possible number of automated voice lines. (The default is 5.) You can open as many CTI ports as the number of Cisco wave devices configured. For example, if you enter "5," you need to create five CTI port devices in Cisco CallManager. If you change this number, you need to remove and then reinstall any Cisco wave devices that you installed.
You can only configure a maximum of 255 wave devices for all installed TSPs because Microsoft limits the number of wave devices per wave driver to 255.
When you configure 256 or more wave devices (including Cisco or other wave devices), Windows displays the following error when you access the Sounds and Multimedia control panel: "An Error occured while Windows was working with the Control Panel file C:\Winnt\System32\MMSYS.CPL." TSP can still handle the installed Cisco wave devices as long as you have not configured more than 255 Cisco devices.
The current number of possible automated voice lines designates the maximum number of lines that can be simultaneously opened using both LINEMEDIAMODE_AUTOMATEDVOICE and LINEMEDIAMODE_INTERACTIVEVOICE.
If you are not developing a third-party call control application, check the Enumerate only lines that support automated voice check box, so that the Cisco TSP detects only lines associated with a CTI port device.
|
Silence Detection
|
If you use silence detection, this check box notifies the wave driver which method to use to detect silence on lines that support automated voice calls using the Cisco Wave Driver. If the check box is checked (default), the wave driver searches for the absence of audio-stream RTP packets. Because all devices on the network suppress silence and stop sending packets, this method provides a very efficient way for the wave driver to detect silence.
However, if some phones or gateways do not perform silence suppression, the wave driver must analyze the content of the media stream and, at some threshold, declare that silence is in effect. This CPU-intensive method handles media streams from any type of device.
If some phones or gateways on your network do not perform silence suppression, you must specify the energy level at which the wave driver declares that silence is in effect. This value of the 16-bit linear PCM energy level ranges from 0 to 32767, and the default is 200. If all phones and gateways perform silence suppression, the system ignores this value.
|
Trace Tab
The Trace tab allows you to configure various trace settings, as illustrated in Figure 47-5. Changes to trace parameters take effect immediately, even if TSP is running.
Figure 47-5 Cisco-IP PBX Service Provider Trace Tab
Table 47-4 contains a list of the Trace tab fields that must be set and their descriptions.
Table 47-4 Trace Tab Configuration Fields
Field
|
Description
|
On
|
Allows you to enable Global CiscoTSP trace.
Check the check box to enable CiscoTSP trace. When you enable trace, you can modify other trace parameters in the dialog box. The CiscoTSP trace depends on the other values you enter in these fields.
Uncheck the check box to disable CiscoTSP trace. When you disable trace, you cannot choose any trace parameters in the dialog box, and TSP ignores the values entered in these fields.
|
Max lines/file
|
Specifies the maximum number of lines the trace file can contain. The default is 10,000. Once the file contains the maximum number of lines, trace opens the next file and writes to that file.
|
No. of files
|
Specifies the maximum number of trace files. The default is 10. File numbering occurs in a rotating sequence starting at 0. The counter restarts at 0 after it reaches the maximum number of files minus one.
|
Directory
|
Specifies the location in which trace files for all Cisco TSPs are stored. Make sure that the specified directory exists.
The system creates a subdirectory for each Cisco TSP. For example, the CiscoTSP001Log directory stores Cisco TSP 1 log files. The system creates trace files with filename TSP001Debug000xxx.txt for each TSP in its respective subdirectory.
|
TSP Trace
|
Activates internal TSP tracing. When you activate TSP tracing, Cisco TSP logs internal debug information that you can use for debugging purposes. You can choose one of the following levels:
Error—Logs only TSP errors.
Detailed—Logs all TSP details (i.e., log function calls in the order they are called.)
The system checks the TSP Trace check box and chooses the Error radio button by default.
|
CTI Trace
|
Traces all messages and function calls between TAPI and Cisco TSP. The system leaves this check box unchecked by default.
If you check the check box, TSP traces all the function calls made by TAPI to Cisco TSP with parameters and messages (events) from Cisco TSP to TAPI.
|
TSPI Trace
|
Traces messages flowing between Cisco TSP and CTI. Cisco TSP communicates with the CTI Manager. By default, the system leaves the check box unchecked.
|
Advanced Tab
The Advanced tab allows you to configure timer settings, as illustrated in Figure 47-6.
Note These timer settings meant for advanced users only rarely change.

Description
|
Synchronous Message Timeout (secs)
|
Designates the time the TSP waits to receive a response to a synchronous message. The value displays in seconds, and the default is 15. Range goes from 5 to 60 seconds.
|
Requested Heartbeat Interval (secs)
|
Designates the time the heartbeat messages are sent from TSP to detect whether the CTI Manager connection is still alive. TSP sends heartbeats when no traffic exists between the TSP and CTI Manager for 30 seconds or more. The default interval is 30 seconds. Range goes from 30 to 300 seconds.
|
Connect Retry Interval (secs)
|
Designates the interval between reconnection attempts after a CTI Manager connection failure. The default is 30 seconds. Range goes from 10 to 300 seconds.
|
Provider Open Completed Timeout (secs)
|
Designates the time the TSP waits for a Provider Open Completed Event. This event indicates the initialization of CTI Manager is done and is ready to serve TSP requests. This initialization time is directly proportional to the number of devices configured in the system. The default value is 30 seconds. Range goes from 5 to 300 seconds.
|
Installing the Wave Driver
You can use the Cisco wave driver with Windows 2000 and Windows NT only. Windows 98 and Windows 95 do not support it.
