3.10. Alternating between calls 
You can make and receive multiple phone calls on OpenScape UC, but only one call can be active at a time. Others can be either incoming calls or calls on hold.
The signaling bars of the various phone connections are represented as tabs in the
tab bar. The tabs of held calls are grayed out. Using the controls in the tabs you
can decide which of the phone connections to deploy for conducting a call. This process
is called alternating between calls.
While connected simultaneously to two or more phone connections:
-
Click on
Hold current call in the associated tab to place
a currently active call on-hold.The call is placed on-hold. -
Click onRetrieve call in the associated tab of the
tab bar to reconnect to a held call.The other call(s) are automatically placed on-hold.
Example
INFO:
It is not possible to alternate/reconnect between incoming calls established on a
preferred
device while using external OND, such as a mobile phone.
Alternating between such calls is only possible thorough the external OND.
