CSTA Message Dispatcher (CMD)
The Wiki of Unify contains information on clients and devices, communications systems and unified communications. - Unify GmbH & Co. KG is a Trademark Licensee of Siemens AG.
The CSTA Message Dispatcher (CMD) multiplexes the CSTA links of multiple applications on a logical link to a HiPath platform. It is used predominantly for connecting the CSTA links on the HiPath TAPI 120 service provider, when insufficient CSTA links on a HiPath platform are free.
The CMD SW-component allows a simple connection of first-party TAPI applications to HiPath platforms, if:
- The number of CSTA interfaces on the HiPath platform are no longer sufficient to connect all TAPI 120-based applications.
- The customer does not have a LAN with Microsoft domain structure.
- The communication server (CTI server) may not be integrated in the customer network/domains.
The CMD message dispatcher multiplexes the CSTA links of multiple applications on a logical link to a HiPath platform. The CMD still offers the following functions:
- CTI firewall, via station number and IP address monitoring
- License control: Each CMD user (for example, HiPath TAPI 120 users) requires a license.
- Support for CSTA Phase III protocol
- Connection to a HiPath platform via Ethernet LAN
Latest Version (effective July 2014) is:
HiPath TAPI 120 V2 R1.70.0
This version supports 32-bit and 64-bit Microsoft Windows operation systems.
CMD general configuration
|TAPI 120||TAPI 120 with CMD|
In a direct connection, the CTI client PC communicates directly with HiPath TAPI 120 TSP via the HiPath platform using Ethernet LAN and CSTA protocols. The number of CTI client PCs that can be connected with TAPI 120 is equal to the number of free CSTA links available on the HiPath platform.
In a connection via CMD, the CTI client PC communicates with TAPI 120 TSP via the PC where the CMD is installed, using Ethernet LAN and CSTA protocols. The CMD multiplexes the CSTA CTI links on individual TAPI 120 TSP systems using a separate CSTA CTI link to the HiPath platform. The PC where the CMD is installed must always be reachable in the LAN for the CTI client PC.
Operation in mixed 32 and 64-bit environment
Within a customer network different Windows operating systems can be used. The released constellations of 32 and 64-bit Windows operating systems, related to HiPath TAPI 120 V2 are shown in the tables below.
TAPI 120 TSP without CMD
|Scenario||PC –operating system||TAPI 120 variant||TAPI client application||Released|
Explanations: A TAPI client PC with 64-bit operating system can operate either 32-bit or 64-bit TAPI applications (e.g. scenario 2 and 3)
TAPI 120 TSP with CMD
|Scenario||CMD PC operating system||CMD variant||TAPI 120 PC operating system||TAPI 120 variant||TAPI Client application||Released|
Explanations: A TAPI client PC with 64-bit operating system can operate either 32-bit or 64-bit TAPI applications (e.g. scenario 5 and 6)
Prerequisites / Requirements
It is recommended to use the “Preferred Software Version” for the given products. The preferred software versions offer higher levels of functionality. However, the CMD software might also operate with older software version with the caveat that recently added interoperability or advanced features may not be possible when using these versions. In cases, if a defect is found when using a backward compatible version, it may be necessary to update to the preferred version.
In general the PC hardware equipment must meet the requirements of the Windows operating system. For each TAPI line configured 200 KB of additional RAM has to be provided.
CMD is still functional with Windows Operating systems for which Microsoft has finished their support. But in case of CMD problem with these Operating Systems, UNIFY will not give any support.
PC operating systems:
- Microsoft Windows 7 (32 & 64-bit) except Starter / Home Premium Edition
- Microsoft Windows 2008 Server (32 & 64-bit)
- Microsoft Windows 2008 R2 Server (64-bit)
Max 1000 CTI Links (CSTA Links)
Functional Boundary Conditions
Due to a resource conflict within the operation system simultaneous operation of CMD 64-Bit and Microsoft Office 32 Bit is not possible. In this case Microsoft Office 64 Bit has to be used or the CMD SW has to be installed on a PC without Microsoft Office 32-Bit
Many documents in various languages are available for HiPath TAPI 120 and CMD. As there are:
- Administration manuals
The documents can be obtained from following sources:
The CMD software is shipped on a CD labelled "HiPath TAPI 120/ 170 V2 Service Provider" which is included in serveral order positions. It is part of the HiPath TAPI 120 SW-package. Installation can done only using the HiPath TAPI 120 setup programm.
For service purposes the software can also be downloaded from the Software Supply Server of the manufacturer. software patches for dedicated problem corrections can be retrieved from the Knowledge Base within the Partner Portal (Partner Portal, login required) of the manufacturer (login required). Access to the two methods mentioned above is only granted by the manufacturer to registered partners on a contractual base.
Use of CMD software itself is not licensed.
Migration from CMD 32-bit to CMD 64-bit
CMD 64-bit is functionally backward compatible with CMD 32-bit. In case of replacement of the 32-bit CMD the deviations within the supported scenarios of CMD 64-bit in combination with TAPI 120 TSP have to be considered.
