The strange thing is, the voicemail folder is empty, which suggests that the voicemail has been delivered correctly. One of my colleagues has carried out some troubleshooting previously, and the UM server can connect to this server on Port 25. I have done some searching of the internet, and no one else seems to have an issue similar to ours.
