4.4. Making a Call 
Making calls directly through your Wi-Fi device is supported in the Voice-only configuration.
You
can initiate a call in this configuration by using the
Dialpad tab.
CAUTION
Do not use OpenScape Mobile Pro to make emergency calls; use your cell phone instead,
as it
provides more accurate location information to the emergency response
center. Emergency calls made with OpenScape Mobile Pro may be routed to the
incorrect response center.
INFO:
The person you call, sees your desk phone number as the calling number.
INFO:
If the connection to the OpenScape Voice Server is lost, calls are made as in UC-Only
configuration.
In this guide the term “Wi-Fi phone" is used to describe phone calls made over Wi-Fi
with the OpenScape Mobile Pro application. The term “cell phone" is used to describe
phone calls made over the cellular network without VoIP. The term "desk phone" is
used to describe your OpenScape Voice IP phone (typically an OpenStage or OptiPoint
desktop phone).
