3.8. Making a Call 
Making calls directly through your Wi-Fi device is only supported in the Integrated
and Voice-only configurations. The UC-only configuration does not support VoIP calls
through your device. So this section refers mainly to the Integrated Configuration.
The UC-only mode enables you to choose the device with which you will perform an outgoing
call.
CAUTION
Do not use OpenScape Mobile Pro to make emergency calls; use your cell phone instead,
as it will
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 will see your desk phone number as the calling number.
INFO:
If 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).
SIP URI Call
You can also perform outgoing audio or video calls, to SIP URI destinations as long
as the PBX
supports such a configuration.
Dial out a SIP URI call with one of the following ways:
- Select the corresponding SIP URI video field on a UC contact.
- Choose a recently called destination from the Call History list.
- Paste an already copied URI on the dial pad.
- Through telephone and SIP URI schemes (“sip:” or “tel:”) provided in other applications (i.e emails, Browsers etc) as long as those schemes are detected as such from the corresponding application. Once the scheme is detected by the system, OpenScape Mobile is listed in the suggested applications to open the URI link for the telephone and sip schemes.
