I have been using fop2 2.26 with voicemail for over a year. I wanted to upgrade to the latest version so I should probably have bought annual maintenance, but I didn't notice that option and repurchased the basic version as we don't use the voicemail option. After entering the code at the command line and doing "service fop2 restart", the panel shows unlicensed. I also tried buying the Annual Maintenance and entering that, but it still shows unlicensed. What should I do?
