Tried that, the 3CX folder is locked to even the Admin PC accountIn my testing, with V18 SP2, you can copy the files (voicemail.wav and voicemail.xml) from the old server to the correct folders on the new server and 3CX will include them. However, new voicemails (generated in the V18 server) will not include an XML file anymore.
How long 3CX will continue to support the import feature is unclear, but I am sure glad they kept the XML processing code active. I hope they never remove this feature (PLEASE 3CX, DO NOT REMOVE THIS FEATURE!).
Founded in 2005, when VoIP was an emerging technology, 3CX has gone on to establish itself as a global leader in business communications.
