Abstract
In the last years the developments of software for VLBI data processing in CASA have been significant. This paper presents the new CASA tasks fringefit and accor, which are closely matched to the functionality in their AIPS counterparts FRING and ACCOR. Several CASA tasks received upgrades to handle the VLBI specific metadata. With the current CASA release VLBI data processing is now possible. Ongoing developments include fringe fitting of broad, non-continuous frequency bands and dispersive delays, which will ensure that the number of use cases for VLBI calibration will grow with future CASA releases.
