We study a method for the implementation of a reliable
teleportation protocol (theoretically, 
of success) of
internal states in trapped ions. The generation of the quantum
channel (any of four Bell states) may be done respecting technical
limitations on individual addressing and without claiming the
Lamb-Dicke regime. An adequate Bell analyzer, that transforms
unitarily the Bell basis into a completely disentangled one, is
considered. Probable sources of error and fidelity estimations of
the teleportation process are studied. Finally, we discuss
experimental issues, proposing a scenario in which the present
scheme could be implemented.
