4.3 By Network (Cellular)

The functionality and features of the AMC are also subject to the used network . If

no data connection is available, features requiring feedback (for example:checking the

status for Call Forwarding) are not available! If Dual-mode usage is part of the solution,

you must make sure the Wi-Fi network is "Voice ready".

Most network operators deactivate the usage of data channels for cellular calls. This

can be avoided by limiting data usage in cellular networks to WCDMA only. Please

note that this setting limits data coverage, e.g. 2G networks, will not be used. No in-call

menu will be displayed in 2G-networks.

Some mobile network operators do not send out their Identity in the signaling available

for the AMC to present in a Network status bar. If this is the case only "Cellular Network"

will be presented.

Please note that updates to lower battery consumption has been implemented on An-

droid OS from version 2.2. To reduce power consumption as much as possible, the

AMC has a conﬁgurable inactivation of the GPRS connection (refer to 12.6). The AMC

will then not continue sending registration requests when the phone enters power sav-

ing mode - unless desired.

There are slight differences in the OS used by manufacturers (HTC, Samsung etc.).

Please note that this can lead to differences in the behavior of the AMC.

Note:

There is no technical support if the AMC runs on a device with altered ROM

(Cyanogen Mod, MIUI and the like).

Which possibilities exist to present Caller-ID information received by cellular chan-

nel are limited by the mobile platform as such.

The Wi-Fi Sleep Policy of the Android operating system (System Settings » Wire-

less & Networks, Wi-Fi Settings » Press "Options"» Advanced ) has to be set to

"Never" for the AMC to work properly. Any other setting here will interfere with

main features of the AMC!

On some older devices and older OS versions the AMC cannot recognize the con-

nection of a headset. Headsets then have to be activated manually by using the

option Loudspeaker in-call menu of the AMC. Bluetooth headsets could interfere

with Wi-Fi systems, as both systems use 2.4 GHz frequency band contention can
