Mobility Extension
SARVAM UCS offers mobility to its extension users whose nature of work keeps them away from their desks
frequently and for longer durations.
Using mobility extensions, the extension users of SARVAM UCS can make and receive their calls from their current
(remote) location, placing calls through the system and can access the system just as any other normal extension
of SARVAM UCS.
SARVAM UCS offers mobility using:
• VARTA UC Clients — VARTA ADR100 or VARTA AMP100. For details refer to the respective User Guide.
• DISA. For details, refer to the explanation given below
How it works
SARVAM UCS supports two types of users:
• Station Users: they are extension users of SARVAM UCS to whom a dedicated physical extension is
provided on their desks.
• Virtual Users: they are extension users of SARVAM UCS who share a physical extension, or may not
have any physical extension allotted to them.
The facility of Mobility Extension is provided to both virtual and normal extension users using the features
“Direct Inward System Access (DISA)” and “Call Forward”.
How to Configure
To provide Mobility Extension to users, follow the steps described below.
• List out the Extension Users and Virtual Users and configure them first.
• Make sure that extensions which are to be provided Mobility Extensions have the features Call Forward
and DISA enabled in their “Class of Service (CoS)”.
• Make a list of External numbers to which the Mobility Extension users will forward their calls. Configure
these numbers in the 'Allowed List' of Local, Regional, National and International Numbers, as appropriate.
• The Toll Control assigned to the extension will be applied when a call is forwarded to an external number.
Make sure that the extensions which are to be provided Mobility Extension have the required “Toll Control”
level for Call Forward to the External Numbers (the numbers you have configured in the Allowed List). Toll
Control level is to be configured on the Mobility Extensions.
• Configure the parameter 'External Call Forward for' on the Mobility Extensions. This parameter defines the
types of calls for which the External Call Forwarding is to be applied. Select any one of the options, Internal
Calls Only, Trunk Calls Only, Internal + Trunk Calls as required.
• Configure the parameter 'DISA' on the trunk lines on which Mobility Extensions users are to be provided
access to. Make sure you select the option 'CLI Auth. Multiple Calls' in the 'DISA' parameter of the trunk
port.
