Restrictions
Please note that there are certain restrictions for third-party applications on practically
all mobile platforms. There are some restrictions on the Android devices which the
AMC is subject to. New smart phone types/models are released every week. To avoid
solution complexity and to ease management, it is recommended to implement a mobile
phone policy in the company to standardize on a limited amount of phone models. A
smart phone is like a computer. You have to reboot them now and then to ensure
consistent behavior (the recommendation is once a day on average).
The AMC is a powerful application, and if you have all features turned on, the AMC as
well as the data connections, battery life can in worst cases be 50% shorter (dependent
on phone type, OS version, network and user scenarios).
There are a handful of destination numbers which are Emergency numbers (000, 110,
112, 118, 119, 911 and 999) which together with your mobile operator’s service num-
bers will result in pure cellular calls ("Direct calls") where the AMC should be inactive.
Please make sure these are not part of your number plan.
4.1
By Mobile HardWare Platform
Samsung phones could need adaption of speech volume on the AMCC for Wi-Fi calls.
4.2
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.
