Community Groups are used to configure bilateral Intercom Calling capabilities and to provide fast dialing for Intercom Calls.
Any Lotus Sametime Unified Telephony subscriber that shall originate or terminate Intercom calls, has to be provisioned with a personal Community Group, defining the allowed Intercom targets/origins.
OScAR-Pro (Lotus Sametime Alarm and Response - Professional) Intercom calls are not applicable to Intercom Community Groups. OScAR-Pro can make an intercom call to any Lotus Sametime Unified Telephony subscriber (device-speaker/mic eqipped or reverts to normal call).
An Lotus Sametime Unified Telephony subscriber S
is able to initiate a 1-way or 2-way speaker call to a destination T
locally or over the SIP-Q network
T is a member of S's Community Group
S is an unblocked member of T's Community Group (if T is a Lotus Sametime Unified Telephony subscriber)
T is in the same BG (Business Group) as S (either locally or during call setup T's gateway is in the same BG as S)
T's device/client is equipped with a loudspeaker (1-way) or loudspeaker and hands-free microphone (2-way) with Auto-answer enabled
T is idle
Otherwise, the call may fail or revert to a normal basic call.
Apart from the group members, the group is provisioned with a Timer for Periodic Tone
that applies to all terminating two-way Intercom Calls. Possible values are:
0, i.e. no tone or
a value between 5 and 180 seconds
The default is 120 seconds.
The table below is a stylized members table:
Table 1. Community Group members table (example)
|COM#||Destination Number||Destination Name||Incoming Block|
The COM# (Community Group Member Number
or COM Number for short) is the (index) number to be dialed after the one-way or two-way intercom access code. This column is searched to identify the destination (member).
For local members, the Destination Number
should be the member's fully qualified directory number. For remote members, the member's calling party number (fully qualified directory number or display number, if configured) must be used instead.
For incoming intercom calls from remote members, the members table is searched for the calling party number to verify that the calling party is an unblocked member.
In any case this number must be routable according to the subscriber's numbering plan.
The Destination Name
field is for descriptive purposes only and is not used for call processing.
The Incoming Block
flag is set on a Community Group member if intercom requests from this person shall be blocked. When blocking is assigned (e.g., value "yes"), then an incoming intercom call from the respective member fails, giving the caller an indication not to use the intercom feature to this party. The caller may re-dial this party as a normal (non-intercom) call.
