I installed unity server with failover at the Head office and remote offices across the country are connected the the central office over the WAN.
When calls are placed from the remote offices to the Head office, voicemail can be left and retrieved.
When calls are placed from the head office to the remote offices and when calls are made between users in remote offices,it gives an error " system error has occured, please contact your administrator" when you want to leave a voicemail.
I need assistance with this please.
Thanks in advance.
