TAPIMaster® 3.2.0 User's Guide
Finer points of using multiple PBXs
There are certain restrictions and points to note when using the software with more than one switch.
•There is support for using more than one switch at once. The switches do not have to be on the same site. Several sites may be brought together so that it appears to the users as though they were all connected to the same switch. When a call is made which the user perceives as an internal call, but which in actual fact is between different switches, the program automatically prepends the necessary area code and main switch number.
•Call pickup for calls at a different site is only possible if the switch supports call transfer to an external destination.
•For the functions listed above only point-to-point connections are supported.
•The larger of the two switches is relevant when configuring the maximum length of the extension numbers.
•A number may not be allocated twice in the line list. For example, extension 230 might exist in all switches but only one of these numbers may be used by the CTI software.
•A network connection is required between the sites. The clients require a connection to the CTI server.
•The server must be capable of controlling the switches – a TAPI driver is required on the server for both switches. One of the switches is then connected via the network. A network TAPI connection is usually available for large switches. For smaller switches, a port replicator could be employed.
•A low-speed network connection to the other sites may have a negative impact on the program performance.
