Hello. We are using YealinkT28/T26 phones on Abyss server. The 3CX is recently upgraded to v.10 and all was working great for a couple weeks after the upgrade.. Issue: Suddenly the message light indication no longer illuminates when new voice mails are received. Secondly, the email notifications that are set up on specific mailboxes are not being generated. All system services have been restarted, and a hard reboot took place late last week. All other phone related functionality seems to be working fine. Any ideas with the MWI would be appreciated. Thanks!
