Remote IP Office systems in the Small Community Network can be associated with another Voicemail Pro server in addition to the centralized Voicemail Pro server. The additional distributed server then provides all voicemail services, except message storage and collection, for their IP Office. This requires the remote IP Office to have licenses for voicemail operation and the features it requires.

While the distributed server does message recording, it forwards all messages to the central Voicemail Pro server. The messages are transferred between systems using SMTP email. For mailbox users, message waiting indication and message collection is still done using the central Voicemail Pro server. With the support of International Time Zone (ITZ) functionality, the users of the IP Office systems located across the globe receive messages in their voicemail system with their respective local time stamp.

• Each IP Office is set up to use Simple Network Time Protocol (SNTP), the time source of the IP Office Network.

• Other IP Office systems continue to use centralized voicemail as normal.

• An IP Office that is using a distributed Voicemail Pro server cannot also be used as the fallback IP Office for the central Voicemail Pro server.

• SMTP SSL/TLS communication is used to exchange information between the servers. If the servers fail to connect using SSL/TLS over SMTP, then plain text communication is used.
