The highy scalable toll collection front end HA-Dispatcher was developed by ev-i Informationstechnologie between 2006 and 2010. In 2011 it was taken over by ITEG.

HA-Dispatcher allows servicing of up to 20.000 simultaneously connected GSM devices for toll projects, smart grid applications or the like.

It is currently in use in the toll project Spitsmijden Brabant in the Netherlands, where 5000 OBUs are in use.
