AASTRA AMC 3 for Android EN - Manual (Page 50)

12 Administrator Settings
12.7.5 Handover Settings
The following settings determine when a handover from a VoIP call to a cellular call
(and vice versa) is triggered.
Automatic Handovers can be enabled and disabled with the checkbox in this section.
The Disconnect Threshold determines when a call will be handed over to the cellular
network, whereas the Connect Threshold is the minimal signal strength for cellular to
Wi-Fi handovers. Also taken into consideration for handovers is the so called Alpha
Value which is a correction factor for the hysteresis function for handovers. Higher
value means more responsive, lower value means sluggish handover.
Note: Normally, there should not be any need to modify these settings. However, if you
think that these handovers happen too late, i.e. if the call quality decreases too much
before the handover is done, try adjusting these settings.
12.7.6 OTA-URL
The OTA-URL is the link to the Aastra administration portal, from where the AMC will
download the configuration (including license), Feature file and LCR file.
12.7.7 Operator Supported Dialing (OSD)
Some operators can call your configured PBX Dialing-in number automatically. Please
note that this will only work with the SIM card for which your AMC was activated. If your
provider supports OSD and if you would like to use it, set this setting to On.
This will only be applied when you are not in a roaming state.
12.7.8 User Account Key
Here you can find your AMC User Account key.
12.7.9 Take Number
Note: This option might not be supported by your PBX.
This setting can be used to transfer calls from your desk phone to your mobile phone.
Please refer to the documentation of your PBX to check if it supports this feature. There
you will also find the information necessary for the configuration of this feature.
