4.5 Starting an inquiry call
You are having a phone conversation and you would like to call another subscriber (Inquiry Call). Then you would like to alternately speak to both subscribers (Call Swap).
Example:
You are speaking to a customer (subscriberA) and you would like to ask someone in the warehouse (subscriberB), whether a certain article is on stock.
You begin a second call at the same time with subscriberB. Then you can alternately speak with subscriberA and subscriberB.
While you are speaking with one subscriber (the corresponding Line button is activated), the other subscriber will hear music on hold.
If you end the call with one of the subscribers (using the handset button), the corresponding line will be free again. You can then switch to the line on hold.
If you were the initiator of the call on the active line and you place the handset on hook, the callers will be connected to each other.
To call an additional subscriber
1 Activate a free Line button during an active connection.
You will hear the dial tone and you can now call a second subscriber.
2 Enter the number (manually or via your Speed Dial or the Phonebook) and wait until the connection is made.
While you do this, the first call will be placed on hold and your conversation partner will hear music on hold. The state of the line on hold is shown appropriately by the animation. () See also
