4 General Operation
4.1 Making Enterprise Calls in Different Networks
The AMC+ enables you to make use of all available mobile networks, mobile data and WLAN networks.
If no data channel is available, no features are offered in the in-call screen of the AMC+. It is not
Please note that the general use of data channels depends on the operating system (Android) of the
mobile phone. Further configuration of the data channel usage policy inside the AMC+ is possible via
Menu>>Settings>>Network Settings. A green (VoIP) or a blue registration icon (signal-only) indicates a
successful system registration. You can choose to use the data channel minimally (restricting feature
usage), dynamically (whenever the AMC+ requires it), or only when not roaming (local network). Your
administrator should have selected the appropriate setting for you during the configuration deployment.
possible
to transmit data during an active call with a 2G connection. Please note that even during an active call, your
active connection can fall back to a 2G connection, or regain 3G connectivity again. So the feature
availability may vary during the call for connection reasons.
4.1.1 Call Handling by Aastra Mobile Client (“Always Aastra Mobile Client” and “Dual
Identity”)
Which calls are handled by the AMC+ is defined by the “Call Preference” setting (Options>>Settings>>Call
Preference). Set this to “Dual Identity” if calls via the native dialer should not automatically be handled by the
AMC+. Use “Always Aastra Mobile Client” to dial all calls via the AMC+ application (including those dialed in
the native dialer).
4.1.2 Mobile Calls
Assuming that the AMC+ is not registered for VoIP, each call you make will be routed via mobile networks.
However, the calls will still be routed through your enterprise PBX:
If you hear waiting tones and the call setup takes a very long time, the data channel connection to the
AMC Controller has failed. The call will still be set up in a fallback mode where the destination number is
transmitted via DTMF. Should this happen on a regular basis or even always, please contact your
administrator to check your configuration.
With a 2G connection it is not possible to transmit data during an active call. Note that even during an
active call you can fall back to a 2G connection, or regain 3G connectivity. The feature display might hence
change during a call.
• Inbound calls: The AMC+ displays the caller ID of the calling party if a data channel is available and if
the Mobile Terminal Call (MTC) number has been set by your administrator.
Note that the data connection to the AMC Controller must have been established before the call
comes in! This connection is also required for the any additional information the PBX provides such
as caller name.
