In a networked trunking system, the subscriber unit user population for a logical grouping of users of the system is often distributed across multiple sites of the network. Group call operations need to span these pop- ulated sites of the network to include all members of the addressed grouping. When a group call request for a grouping with user population distributed across multi- ple sites is received, call resources at each of these pop- ulated sites is required to assure maximal participation in the group call. However, in an attempt to reduce ini- tial system access time for the processing of these multi- ple site spanning group calls, the call process may begin when the site of the group service request and a subset of the sites supporting group members for the requested grouping have adequate call resources for assignment. As call resources become available at the other group- ing populated sites, these sites join the call already in progress and will be treated as active members of the Cdl.
