General information

This information is generally required by support for every support case:

  • System ID (XID) (you can find this on the XPhone Connect Server-Web Administration start page)

  • XPhone Server and Client version

  • Since when does the behaviour occur (was there an update etc. change of settings)?

  • Has it worked before?

  • How does the behaviour occur and where does it happen?

  • Is this behavior sporadic, or too completely reproducible?

  • Is only one user / one location affected or are all users affected?

Problem-related information

Depending on the topic, we need more specific information:

  • PBX system (incl. version)

  • Information on the system environment (operating systems (server and client, bit size), virus scanner, etc.)

  • Version of Outlook / Exchange / Notes

  • Headset (for softphone)

  • Ist the XCC outsourced?

In most cases, additional log files are needed for analysis. Depending on the topic, we need the appropriate files. Here are a few general examples:

The logs are also not mandatory at ticket opening, as we need different logs in more specific cases.

The information about which logs are needed and how to create them can be obtained from our support, if necessary.

If the log files exceed a size of 20MB, you can use our FTP upload to provide us with the files.

Use these access data for this purpose:

  • FTP-Server:

  • User: FTPSupport

  • Password: FTPSupport

Note that you cannot see the contents of the server. There is only write access.

We need feedback as soon as the files are uploaded. We also need the names of the transferred files to be able to map them to this ticket.


If you have created log files according to our instructions, please send us complete log files and not individual files or text excerpts For each log, we require an exact description of the event, which contains the time of the error, the involved phone numbers and the observed behaviour, etc.
