AASTRA AMC 3 for Android EN - Manual (Page 47)

12 Administrator Settings
12.4.2 Mic ALC
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.
12.5 Network Settings
The following settings manage the use of Packet Data for all services offered by the
AMC.
12.5.1 Network Preferences
Unlike Wi-Fi connections, cellular connections cannot carry data. Availability of data
channels depends on your provider and on your contract. Many contracts come with a
certain amount of data traffic included Packet Data.
The Packet Data settings described here allow you to determine if and how the AMC
is allowed to use cellular Packet Data. You can choose to generally disable it for the
AMC (Off ), use it exclusively for HTTP(S) requests (Minimal, i.e. Corporate Contacts
access, HTTPS Callbacks etc.), or allow its usage only in your provider’s network (Local
Network ). To use it whenever needed for a system registration (no Voice over 3G) set
this to GPRS Dynamic.
Local Network + Roaming = Minimal
Please note that while in roaming in other provider networks and while the
setting Local Network is active, the actual usage of the cellular data channel
is done according to the setting Minimal, i.e. registrations are not possible
and only HTTP(S) requests are allowed.
Native Settings Dependent
Smartphones have preference options to enable or disable the use of packet
data. If turned off in the native menu, any preferences made within the AMC
remain without effect!
Costs and Battery Life
Please note that the usage of data channels may drain the phone’s battery.
If costs run too high, a provider might also disconnect the call. Section
5 on
page 13 contains information about the amount of data consumed by certain
features.
