Abstract
A system [100] includes a target set of communication devices [105] for a group call. An originator communication device [102] transmits a group call initiation for the group call. A communication and processing device [125] sequentially invites the target set of communication devices in response to detecting at least one predetermined characteristic of the group call. The sequentially inviting the communication devices comprises (a) initially inviting a first subset [130] of the target set of communication devices that comprising required communication devices, (b) subsequently invites a second subset [135] of the target set of communication devices in response to determining that the group call will be initiated, and (c) joins targets of the second subset of the target set of communication devices accepting the call initiation message to a communication session involving first targets of the first subset of the target set of communication devices accepting the call initiation message.
