Voicemail storage backend has been migrated from Zimbra mailserver to Asterisk file system.
All customer voicemail accounts and saved contents have been moved.
Reason for migration:
Random Asterisk crash caused by the IMAP Lib that connects Asterisk and Zimbra server (as a voicemail storage server).
IMAP Lib is not an official Digium component.
It is a contribution by University of Washington.
It had a number of shortcomings to begin with and we managed to overcome one after another.
However we could not fix the memory segmentation fault and resulting random crash after spending so much effort.
