13.3 Call Transfer
When you use the Mobility Extension station, you can transfer calls as if you used an internal fixed line. Unlike with fixed stations, use the code 7* for transfer to the Mobility Extension, which is an equivalent to the FLASH key. Calls can be transferred to phone numbers both inside and outside the 2N® NetStar communication system. Using the call transfer code 7* you can also enable the Call Swapping or Return to Transferred Call services from your Mobility Extension.
Call Transfer to Mobility Extension
Like with an internal station, transfer to the Mobility Extension can be with or without hang-up. One and the same transfer code is used in either case but the transferring procedures are slightly different. Dial:
7*nn
where nn is the number of the subscriber you want to transfer the call to.
Transfer with Hang-Up
Example: Suppose you want to transfer (with hang-up) an active call from your Mobility Extension. During the call dial 7* and the selected phone number. The caller hears music and is waiting. If you hear the alert tone, you can hang up to transfer the call to the selected subscriber and the person under transfer hears the alert tone. If you hear the busy tone, no call transfer can be made as the selected destination is busy or unavailable. In that case return to the person to be transferred by re-entering 7* and either end the call or transfer it to another subscriber.
Transfer without Hang-Up
Example: Suppose you want to transfer (without hang-up) an active call from your Mobility Extension. Dial 7* and the selected phone number during the call. The caller hears music and is waiting. If you hear the alert tone, wait till the transferee answers the phone and then either hang up to complete the transfer, or enter 7* to return to the original call. If you hear the busy tone, the transfer cannot be completed as the selected destination is busy or unavailable. In that case return to the person to be transferred by re-entering 7* and either end the call or transfer it to another subscriber.
Returning to Transferred Call or Call Swapping
Use this service when you have put one call on hold and are speaking to another subscriber in an active call. Dial:
7*
Example: Suppose you are calling to the communication system from your Mobility Extension and have put one call on hold and are making another call. To activate to the subscriber on hold push 7*. Now you are speaking to the subscriber originally put on hold and the other subscriber hears the Music on Hold. By re-pressing 7* you swap the two calls.
Active Call Termination
Basically, there are two situations in which you can use this service. In the first case you have one call on hold and want to terminate the current call, and in the other case you have an active call and want to dial another destination after terminating the active call.
9#
Return to Call on Hold with Active Call Termination
When you have put a call on hold and want to terminate the active call to return to the one on hold, use the Active Call Termination service. Using this service you disconnect the active call (the opposite party hears the busy tone) and get connected to the call on hold.
Example: Suppose that two calls have been established on your Mobility Extension (both via 2N® NetStar). One of the calls is on hold (the subscriber hears the Music on Hold). To terminate the active call and get through to the call on hold, dial the code 9#.
Active Call Termination with Further Dialling
The case is quite different if you have established one call only and want to terminate it. After a standard hang-up, you have to call the 2N® NetStar communication system for a new call. To save the call setup costs, use the Active call Termination service.
Example: Suppose you have established just one call on your Mobility Extension and want to terminate it to be free for another internal call. Press 9# during the call. The current call is disconnected and you get the communication system dialtone again. Dial the next subscriber number and a call will be set up like the first call.
