Configure telephone system

Normally you do not have to make settings in the PBX system. Here are some hints for special settings.

CSTA performance feature
In the Hipath manager under settings - system parameter - PlusProducts-Flags:

CSTA application activeFor information only, no functional effect
Direction prefix send via CSTAIf enabled (recommended) the outside line access codes are sent with the phone numbers reported by the PBX to the PC.
enhanced CSTA-CAUSE handling activatedIf enabled (recommended), additional information is transmitted using CSTA.
CSTA with CSPIf enabled (recommended), additional information is transmitted using CSTA.
Blind TransferNo effect on ECSTA.
MULAP monitoringIf activated, MULAP group phone numbers can be used with ECSTA. Additionally, see also MULAP Monitoring <

Open numbering scheme
Operation with the performance feature is supported. Details are found on page open numbering <

Operation using an ISDN card
The phone number for the D-Channel access is normally 891. To guarantee a proper data transfer, you should increase the USBS values in the Hipath to the following values:
In the Hipath manager under settings - lines / integration - ISDN parameter - USBS:

  • Hicom 150 - V2.2
    x-Parameter: 128
    y-Parameter: 64
  • Hipath 3000
    x-Parameter: 200
    y-Parameter: 200

Connection using a serial cable:
Make sure that the driver settings match the Hipath settings. The baudrate of the Hipath may be changed using a Optiset system telephone:
*95 = Login / Password
22 = System settings
13 = V.24 Settings
1 = baudrate,MB
*3 = 19200 Baud

Connection using a network (TCP/IP)
The default TCP port for the CSTA connection is 7001.
In order to connect the estos ECSTA for HiPath 2000/3000/5000 to the Hipath using TCP/IP, you need a Hicom 150H/ Hipath 3000, an Xpress@LAN or HG1500 or a LIM Module.
Please make sure to enter the IP adress of the Hipath itself, not the one from the Xpress@LAN (HG1500). In the Hipath configuration you will need to configure the following values:

  • In network - IP parameter: HIS forwarding, IP Address of the Hipath must be entered.
  • In network - communication partners: IP-Applications: check CSTA.
