Abstract
Conserving call logic during handoff may be provided. First, a call may be received at a first server. Next, the first server may determine that it cannot handle the call. Then the call may be transferred by the first server to a second server with enough information so that the second server can take up the call where the first server left off. Transferring the call to the second server with enough information so that the second server can take the call up where the first server left off may comprise placing the information in a REFERRED-BY header and sending the REFERRED-BY header to the second server.
