Abstract

The present invention provides a method for establishing a multi-user call in a communication system. The communication system receives a call request to establish a group call with a shared group of users. The communication system determines which of the plurality of individual users should be excluded from the call and connects each of the group of included users to establish a multi-user call. The communication system preferably indicates that a unit was not currently available, for example by playing a prerecorded message, playing a tone and also preferably indicates why a unit was not available.
