Alternatively, the caller ID of the calling party can be transmitted in the mobile network
signaling
if your PBX is connected via a CLIP no screening trunk. Please ask your administrator if
the procedure is not clear to you.
• Handover: If an accessible WLAN access point (AP) of sufficient quality is in range, the AMC+
passes the call automatically to WLAN. This can also be done manually in the in-call screen (>>
Options). To differentiate between a VoIP call and a mobile call watch for the green mobile phone
icon on the right top that is always visible if a call is routed via mobile network.
4.1.3 VoIP Calls
• Outbound calls: VoIP calls will only be performed when the registration icon is displayed in green.
• Inbound calls: The AMC+ will come to the foreground when a VoIP call comes in. When this
happens, there is little difference for the user compared to an incoming mobile call.
• Handover: If signal strength decreases to a point where the voice quality suffers, the AMC+ will
perform a handover to mobile networks (this can also be done manually in the in-call screen).
Automatic handovers have to be enabled in your Aastra Mobile Client’s configuration. Ask your
administrator about this.
4.2 Call Types
To use other call types do the following:
1. Enter or select a number
2. Open the main menu
3. Select “Call type pre-selection”
4. Then choose the desired call type:
a. Direct: for by-passing the PBX .
b. Callback: Using “Callback” calls are reversed in direction
(outbound call is turned into an inbound one automatically without
user intervention). This feature reduces costs when making calls
from abroad (ask your administrator if more information is
required).
c. Call-through: The call will be routed via your corporate PBX and
enable feature use if the required data channel (WLAN or 3G) is
available.
d. Dynamic: Using this option calls will be routed as demanded by the
configuration of the AMC+ (your administrator has the possibility to
preconfigure a certain call type for certain numbers or pattern).
