Overview of Functions
For a CTI solution, the PBX can be connected to a local network (CTI server and CTI clients). In order to do so, a CTI software such as PBX Call Assist is required.
Further help under LicensesAs an alternative, we recommend the following software manufacturers:
•ESTOS (estos)
•ilink (ilink)
The LAN-TAPI provides the TAPI 2.1 interface over the Ethernet port on the PBX.
A Microsoft server then distributes the functionality throughout the network (third party network connection) onto the separate Microsoft computers so that telephony software, e.g. PBX Call Assist or other TAPI applications can use the TAPI functions. The PBX is addressed by the server over the Ethernet interface. When a user wants to dial from the client PC, the command is forwarded to the server. The server signals this to the PBX which then establishes the connection.
LAN-TAPI supports the following phones connected to the PBX:
•Analogue phones
•Standard VoIP phones (SIP)
If a user is using TAPI on several telephones, they must specify which telephone is controlled by TAPI. This specification is not dynamic and does not change when the user switches from one telephone to another. Initially, the first telephone that was assigned to the user is the one that is active. If the user wants to use a different telephone, they must actively set it as the TAPI telephone.
Functions
LAN-TAPI supports the following functions:
•Display of the called MSN (multi-company operation)
•Call forwarding (CFU, CFB, CFNR)
•Call deflection (forwarding before call acceptance)
•Transferring calls
•Splitting a call
•Monitoring (status display of the private branch exchanges)
•Pick-up
•Do-not-Disturb
•Blind transfer using ESTOS
Important: The possible functions are dependent on the end devices/applications used.
Note: For controlling a telephone of the COMfortel D-series via LAN-TAPI, the CTI Access Token is required (from firmware version 1.4 of the telephone). The code given by the PBX for each phone is transmitted to the phone by provisioning.Configuration
