Numbering plan

The following numbers are already used by the system:

700, 701-720, 801, 900, 901, 902

In the Users/telephones menu, you can create SIP users for logging on your terminals.

Number of terminals

Three telephones / SIP clients can be registered per SIP user. Otherwise, the devices for which the login time expires first will not respond to incoming calls. Since the logon occurs every few minutes, different terminals would ring at different times!

So, if a participant wants to use several terminals (e.g. when working from home and in the office), you should consider carefully whether you want to use several devices for one user. If there are multiple devices for a user, they will not be reachable via different telephone numbers. This also gives you no flexibility for outgoing calls as different numbers cannot be used here.

Create user

Below the user table, a user can be created and configured using  or you can use Launch quick start wizard.

The quick start wizard

The quick start wizard greatly reduces the time and effort required to set up a user. If you create the user using the quick start wizard, the necessary settings for the CTI client/softphone are automatically made, the provisioning of the telephone is prepared and the callthrough rules for wwmobile are created. After setting up the user in this way, it is possible, as before, to adjust the settings to your requirements in the various menus. The quick start wizard provides you with useful explanations of the individual fields to be filled in.

Set-up tip

With the quick start wizard, the workload is reduced and fewer settings are forgotten.

Additional configuration of users / telephones

Access data

  • Activation link: Here you can create an activation link and send it protected with a password to set up the wwphone easily. This allows the administrator to leave the setup to the end user with simple instructions.
  • Username: This is the username with which the terminal must log on to the switchboard. This is also the name by which the telephone is identified and displayed in dial plans, call statistics, etc.


This field may only contain the following characters: a-z, A-Z, 0-9, - and _

When using MS Teams here, use the first part of the Teams username, e.g. Teams login with would then have to use the username

  • SIP password: Defines the password with which the terminal must authenticate itself. We recommend the automatically suggested password.
  • CTI password: Defines the password with which the user can authenticate himself via CTI client (wwphone), via the wwmobile app and via the fax printer driver. We recommend the automatically suggested password.


    Choose strong passwords. There are currently hackers who are specifically targeting switchboards. These do not look for security holes, but for weak passwords. Although IP addresses are automatically blocked after a few unsuccessful authentication attempts, we recommend that you choose passwords that are as complex as possible.

User details (display and phone book)

  • First name: The first name of the participant (optional).
  • Surname: The surname of the participant (optional).
  • Mobile phone: The mobile phone number of the participant (optional).
  • Nickname: The name to be displayed in the online list of the wwphone and CTI client.


  • CTI: The current presence status of the relevant user is displayed here (Telephone service, Available, Be right back, Direct number only, Internal only, Unavailable). The Offline status means that the wwphone client is not connected to the vPBX.
     By clicking on the icon behind the CTI status, the history of the switchovers is displayed in order to detect operating errors.


The logs are deleted when the PBX is rebooted.

  • Telephone: Here you can see the status (offline, free, busy) of the terminal. If you have connected a second telephone, busy is displayed if a terminal is busy.

Other settings

Online statistics

If you click on the  icon next to a user/telephone, a window opens with the response statistics of the corresponding device. Response time is measured at SIP level by sending an options packet to the terminal and measuring the time it takes for the response to reach the switchboard. In this statistic, you can see clearly when a device was logged in and reachable and when it was not. If all of the fields are green, it means that the connection is and was OK. If, on the other hand, many fields are orange, your Internet connection is probably overloaded or too slow. If red fields appear again and again, even though the telephone was constantly connected to the Internet, you may have a router or firewall that is interfering with the communication between the terminal and the switchboard! In this case, please read the Tips and troubleshooting section carefully!
