Call queueing allows calls to be placed on hold without handling the actual enquiries or transferring callers to the desired party. While in a call queue, the caller is played pre-recorded music or messages. Call queues are often used in call centres when there are not enough employees to handle a large number of calls. Call centre operators generally receive information about the number of callers in the call queue and the duration of the waiting time. This allows them to respond flexibly to peak demand by deploying extra call centre staff.

With call forwarding, you can forward your calls to a specific destination depending on a chosen scenario. You can create your personalised profiles for certain scenarios, e.g. "Vacation", and set a target phone number to which calls can be forwarded to.

Each user has an automatically set call forwarding profile – the default profile – with the following properties:

• It does not have source-based call forwarding

⇒The circle has a blue dot inside it, which means that the profile has been selected.

You have created a profile "Vacation". To define exactly what this profile should do, you can either activate one of the call forwarding conditions

• Always
• Busy
• No answer
• Not registered

or you can set a rule and use source-based call forwarding (for more information, see Source-based call forwarding).

There are four call forwarding conditions, Always, Busy, No answer and Not registered.

2. Select a call forwarding destination via the Destination dropdown below the call forwarding condition. You can select between three options, Voicemail, Busy and Phone number.

What do the call forwarding conditions mean:

• Always

Please note that if this forwarding condition is active, it will influence the call destination on Global DND. That means that Global DND will have the same call forwarding destination as defined here.

• Busy

The call will be forwarded if your extension is busy. The caller receives a busy signal and will then be forwarded to the defined destination.

Please note that if this forwarding condition is active, it will influence the call destination on Global DND. That means that Global DND will have the same call forwarding destination as defined here.

• No answer

The call will be forwarded if you do not answer within a defined time limit. The caller receives a waiting signal and will then be forwarded to the defined destination.

The time limit can be set to 5, 10, 15 or 20 seconds by clicking on the number dropdown.

• Not registered

The call wil be forwarded if your device is not registered on PBX (e.g. broken cable etc.). All incoming calls will be forwarded to a defined destination.
