I configured everything for the IP office, including the Voicemail Pro license, before setting up the Voicemail Pro server. The license was confirmed as valid before it was pulled out of production (I have the screenshot also). When I added the license and saved the configuration/restarted, the license went into Valid state. It remained in that state for the next few days. I finally got around to installing the Voicemail Pro server and when I went back to configure voicemail for the users in Manager, I noticed it was N/A. When I went back to licenses the state is now Invalid. Could this be caused by the version of Voicemail Pro that is installed? Are there any other things that could be causing this license to now be shown as Invalid? It is a non-expiring license for 250 users. Thanks in advance!
