10.1.8 MTC Number
MTC stands for Mobile Terminated Call. The MTC Number will be associated as Caller ID for your
corporate system (AMCC). You could say that this is the identification the AMCC uses towards the
AMC+, and it can be used when an operator uses CLIP-call screening. If the MTC Number is set,
all Enterprise calls must come with this Caller ID otherwise they will not be handled by the AMC+.
In order to make sure that the number is positively matched, you have to enter your PBX number in
international format.
Use Case
The MTC Number or prefix identifies a call as an Enterprise (AMC+) Call. All AMC Solution features
become available for identified Enterprise Calls. A 100% match of the MTC Number is required for
the transmission of Caller IDs (refer to
8.2 ).
Note: To be able to present some Caller ID information when an operator uses CLIP-call screening,
the AMC+ introduces an entry in the Contacts if an MTC number is set in the client configuration. The
entry is removed whenever the AMC+ is exited.
10.2 Dual Mode Settings
Select Cellular Only, Single Mode or Dual Mode:
If set to Cellular Only, the AMC+ will only allow connections to cellular networks.
In Single Mode it allows cellular networks and Packet Data for signaling ( Packet Data and/or WiFi,
this depends on the device), i.e., if you want to have SIP signaling over Wi-Fi but call-setup signaling
and media over the cellular network, you need to select the Single Mode setting!
The setting Dual Mode allows Voice-over-Wi-Fi, but it requires that the Android device supports Wi-Fi
and that the required settings in the native OS are made.
Consumption of Packet Data
The Packet Data setting lets you specify when packet data (for example Packet Data) should
be used; refer to
10.4 .
Native-Dialer Dependent
Whether a data channel is established via Wi-Fi or via Packet Data depends on the Network
Preferences you have chosen in the native Android application. If a preferred Wi-Fi network
is available, this network will be used for the data channel.
