The Plum Voice Portal web interface is currently limited in that the administrator cannot configure a DNIS to '0'. Plum recommends using 4 or 5 digit DNIS values that match your current phone numbers sent to the system (i.e. 2012, 2013, 2014, 2015).
If you have set the DNIS to '0' you may notice some strange behavior in the 'Applications' and 'Users' Pages. To correct this behavior, go to the 'Server Config' page and make sure none of channels on the plumvp are set to '0' or have a range starting at '0'.
