Field nameDescription
Parallel ringing

Enter any additional number to which the call can also be forwarded to. This is usually your mobile phone. In this case, the system telephone and the mobile phone both ring and you can then choose which phone to answer. If, for example, the call is answered with the mobile phone, it can no longer be answered with the PBX phone.

Signalised number on call forwardsDefine the telephone number which will be shown to the target recipient.

The following options are available:
a) Show the caller’s telephone number
b) Show the the callee’s telephone number
c) Show the telephone number of the forwarding extension.
Allow external numbersHere, you can determine whether or not this specific extension is permitted to configure call forwarding to outside telephone numbers. However, you can also specify globally for all extensions whether or not external telephone number are permitted. This can be done in the menu item Administration 5.1 Profile.
Profile

Profile refers to the call forwarding profile. Create a new call forwarding profile or edit existing call forwarding profiles. Up to 10 call forwarding profiles are available per extension. One of the profiles is the default call forwarding profile, which is automatically available on each extension.The other 9 call forwarding profiles can be freely defined by the user.

Rule set

Define a rule set for a call forwarding profile. Four call forwarding conditions are available in a rule set. Here you can define what should happen with an incoming call.

SourceSource of the incoming call, e.g. all calls (catch all).
DefaultCall forwarding condition: destination for unconditional call forwarding. A call is always forwarded to the number defined here.
Busy
 
Call forwarding condition. Here you define to which destination the call will be forwarded to, e.g. a different phone number or voice mail, if your extension is busy.
Not available
 


Call forwarding condition: You do not answer the incoming call within a defined time period (timeout). The timeout can be set to 5, 10, 15 or 20 seconds. Here you determine where the incoming call will be forwarded after the specified time has elapsed. The caller receives a call waiting signal and is then forwarded to the defined destination.

Timeout (seconds)Timeout for the extension, i.e. after how many seconds the caller will be forwarded accordingly. The timeout applies to call forwarding in case of no answer.
Not registeredCall forwarding condition: Your device is not registered on the telephone system (e.g. broken cable etc.). All incoming calls will be forwarded to a defined destination. The caller will then be forwarded directly to the defined destination.

Parallel ringing

Usually, you assign here your mobile telephone number. In case, you have a ssigned your mobile telephone number, the extension AND on the mobile device will ring. You can now choose what device you prefer to take the call on. If you select your mobile device, then it is not possible to redirect the call to your extension.

If a call forward is set to an external number, e.g. a mobile device, a dial prefix has to be added. Example: 0 0049 171 xxxxx.
