Using Mobilink we will have an identical database in 3 different locations.

Non UM users will have their messages stored in 2 locations. (Voice Server X and File Server)

The architecture will guarantee 100% Uptime for Voice Services. (PBX Dependent)

All messages are globally unique

Some specifications

Distributed architecture:

Application can be distributed over min 3 max 9 servers

Voice Server > 2-8- Active servers connected to PBX’s

DB Database Common > 1 manages synchronization of all the Voice server nodes

Nodes can be distributed in geographically independent location connected to different PBX’s

Integration: SIP to SIP trunk or extensions, SIP to TDM -gateways

Port Density: 100 sip ports per server- 800 voice ports

20000 plus users-Voicemail/Unified Messaging

Licensing Only one Hard Key-Sentinel is require. Multiple Voice Server Administration Allows for allocation of a single License over multiple servers If Total of ports is 800 they can be divided among multiple servers. Heart Beat checks for hard key. When not available, channels will be disabled within 4 days.
