XPhone Connect 9 System Requirements

The recommendations given here are based on average usage values. As system complexity increases, so do the system requirements.
Your ICT partner will be happy to advise you on the specific requirements for different systems or scenarios. C4B partners can find all information in the partner portal (XPhone Connect Sales Whitepaper).

 
 

Important Notes

The system requirements for the use of XPhone Connect depend on various factors: 

  • Operating mode (e.g. UC server, directory service & fax server, directory service only or as web service)
  • Frequency of use of the various UC services
  • Call volume
  • Number of users
  • Number of IP channels
  • Number of connected databases & contacts


Below you will find recommendations based on average usage values.

As system complexity increases, so do the system requirements. Your ICT partner will be happy to advise you on the detailed system requirements for different systems or scenarios, e.g.:

  • Use of an SQL Standard/Enterprise Server (on the same or another server)
  • Use of different databases and the number of their contacts
  • Effect on multiple PBX nodes, dialling parameters
  • Maximum number of simultaneous conference call participants
  • Use of Softphone (Desktop & Mobile)
  • Use as a directory service with fax
  • Use as a directory service without fax/voicemail
  • DMZ: provision of Mobile/Analytics websites
  • DMZ: provision of the outsourced XCC for Softphone Mobile & Softphone use in the home office (Payload Separation)

C4B partners can find the detailed system requirements in the partner portal ("XPhone Connect Sales Whitepaper").

Notes on installation

C4B sales partners can find detailed planning information in the sales white paper. 


Notes on migration

  • XPhone Connect Server Version 8 is NOT compatible with XPhone Connect Client Version 9.
  • XPhone Connect Client Version 8 can be operated (e.g. in migration scenarios) on XPhone Connect Server Version 9, but only with the features described under Version 8. Restriction: Push Notifications to a Mobile Device are always sent when an XPhone Connect Client Version 8 is operated on an XPhone Connect Server Version 9.
  • If you want to use the latest features, you must use XPhone Connect Client Version 9.
  • Please read our instructions for migrating SQL Server 2014 Express to SQL Server 2019 Express before you upgrade the server! You'll find the instructions in the DVD image in the "Documents" folder.
  • If you also want to use the new features with the XPhone Connect Mobile Client, it must be operated on an XPhone Connect Server Version 9.

1 Memory for the entire system. XPhone as the only server application besides Microsoft SQL Express.
2 Free disk space for XPhone Connect. If the internal memory (fax, voicemails, chat, journal) is used intensively, the capacity may need to be increased.
3 A core in the sense of the system requirements corresponds to the efficiency of a modern server CPU (comparable with Intel Xeon processor E7 V4) . In virtualised environments it must be ensured that the performance is available to the guest operating system at all times (dedicated core).

 
 

Softphone

The maximum expansion level of the softphone must always be calculated by the number of calls, as transcoding requires the most computing power. Please note that the following table shows simultaneous calls and that there is a considerable difference between internal and external calls. 

For the calculation, the number of cores for internal and external calls must be added.

Note: With an outsourcing of the XCC, the expansion stages can be increased. C4B sales partners can find detailed information in the sales whitepaper.

Separate system requirements

For other application scenarios and quantity considerations, the system requirements may differ. Please contact your ICT partner for the following application scenarios. C4B partners can find the separate system requirements in the partner portal ("Sales Whitepaper").

  • XPhone Connect and SQL Server on different machines
  • For more than 500 users, use of an SQL Server (Standard/Enterprise Edition) is required. This is usually installed on the same machine as XPhone Connect and provides the best possible performance. The use of XPhone Connect and SQL Server (Standard/Enterprise Edition) on different machines is also supported. This allows the use of an existing SQL Server.
  • Increased system requirements when using the Call Controller (XCC) with AnyDevice and/or Conferencing: The system requirements depend on the number of users who use these services as well as on the expected call volume.
  • Increased system requirements for additional UM IP channels (fax, voicemail, Auto Attendant) and PBX nodes
  • Use as a directory service with fax
  • Use as a directory service without fax/voicemail
  • DMZ: provision of Mobile/Analytics websites
  • SoftphoneWhen using softphones, additional CPU cores are required depending on the call volume. An overview of the required cores in relation to the number of calls can be found under "Expansion stages" (see above).

Webfrontend

(Administration)

  • Firefox version 71 and higher
  • Chrome version 79 and higher

Virtualisation

  • VMware ESXi 7.0
  • Microsoft Hyper-V 2019
  • Microsoft Hyper-V 2016
  • Citrix Xen Server 7.1

    When connecting UM services in virtual environments, sufficient system capacities for the XPhone Connect IP channels (XCAPI interface) must be available at all times. A dedicated processor core is necessary. For more information, see the technical documentation for XCAPI.

    In a virtual environment, the virtualised computer must also use the hardware timer of the host system, since purely virtualised timers are usually not precise enough for voice transmissions.

    For detailed information regarding hardware/virtual timers, please refer to the documentation provided by the virtualisation provider.




    Interfaces


     

    CTI services

    For CTI services a compatible PBX system with enabled CSTA/TAPI interface is required.

    The TAPI driver must be able to monitor all lines of the PBX system.

    • Full XPhone Connect-Outlook integration is only guaranteed if both the XPhone Connect Client (including Outlook plug-in) and Outlook are installed on the terminal server.

    The following restrictions apply when Outlook is running in a different environment than the XPhone Connect client:

    • The XPhone Connect Outlook plug-in (integration of CTI, UM, conference calls, presence) can not be installed.
    • Private Outlook contact folders must be connected centrally via the XPhone Connect Directory. A client-side connection is not possible.
