DK424 - Single station does not roll to vm on no answer or busy

[hdokes]

Have customer with a major dk424 installation using 5 expansion cabinets. All systems are good with exception of two extensions (2014 and 2015) which are working as needed and have voice mail boxes configured and accessible however neither extension will pick up to voice mail on no answer or busy when dialed internally from another extension. They ring indefinitely.

Neither of these extensions have been used until now since initial install.

I have little experience with toshiba systems. Work mainly on Avaya, Panasonic, and Meridian systems.

Any ideas would be much appreciated.

Thank you.
