AASTRA AMC 3 for Android EN - Manual (Page 35)

11 User Settings
Note: Emergency numbers do not have to be specified here, as they are treated sep-
arately. The major emergency numbers for all continents such as 112 and 911 are
preloaded in the AMC. If you have any special or regional numbers however, you can
configure them here.
11.2 Dual Mode Settings
Select Single Mode or Dual Mode:
In Single Mode it allows cellular networks and Packet Data for signaling (Packet Data
and/or Wi-Fi, 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
12.5 .
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 applica-
tion. If a preferred Wi-Fi network is available, this network will be used for the
data channel.
11.3 VoIP Settings
11.3.1 Mic Volume
Increase or decrease the volume of your microphone, i.e. the input volume, with this
setting for VoIP calls. The default setting is "0". The range from -4 to 4 is supported.

This setting enables automatic volume control (”clipping prevention”). An algorhythm
using "Max Index Spread" and "Max Loops" sets the effect of this setting. Please do
not alter these settings, unless advised to do so.
