Claim:
A method for conserving call logic during handoff, the method comprising: receiving a call at a first server; determining that the call cannot be handled by the first server, wherein determining that the call cannot be handled by the first server comprises: determining that a voice mail box associated with a called party associated with the call is not located on the first server, querying a database on a network to determine where the voice mail box associated with the called party is located, and determining that the voice mail box associated with the called party is located on the second server; and transferring the call to the second server with enough information so that the second server can take up the call where the first server left off, wherein transferring the call to the second server with the enough information so that the second server can take up the call where the first server left off comprises enabling the second server to transition to a point within a state machine where the first server left off, the point within the state machine representing a location and a context of the call where the first server left off.
