We have 2 Unity Servers. We have issue in receiving voicemail in one of the Unity server but it is fine if i failover to the other Unity.
When we the problem Unity is active, We do not get a voicemail message when some left a voicemail but the caller will get the greeting/prompt to leave a voicemail.
We can also access the Unity voicemail box but there are no new messages even though we did leave a voice message.
It is fine when the other unity is active.
Does it have something to do with permission issue?
Thank you for your help,
