Architecture: What's Your Favorite Flavor of UM?
CallXpress is the most flexible Unified Messaging solution on the market today, allowing enterprises to choose how they deploy and use Unified Messaging. Unlike other solutions, CallXpress lets administrators deploy any type and mix of Unified Messaging as well as to combine Unified Messaging and traditional voice mail users on the same system, via simple configuration changes. CallXpress supports all four of the popular Unified Messaging architecture types; Server-based Unified Messaging, Client-based Unified Messaging, Secure Unified Messaging and Simplified Unified Messaging.
Server-based Unified Messaging
All messages — voice, fax and e-mail — are placed into a single store on the e-mail server. This allows users to access their voice messages from whichever e-mail client they choose — including desktop e-mail program, telephone, web-based e-mail access program and their PDA e-mail program.
- Ideal for mobile users
- Easiest to use remotely with a laptop computer
- Fully leverages e-mail system features (e.g. Archive)
- Supports the widest range of interfaces and devices

Client-based Unified Messaging
Voice and fax messages remain on the CallXpress system, while e-mail remains on the e-mail server. This dual message store version of Unified Messaging integrates voice and fax messages access from their desktop e-mail client and telephone while minimizing the impact on the LAN and e-mail message store.
- Ideal for companies that require separate message stores
- Less of a traffic load on the network
- Less storage load and activity on the e-mail server
- Non-Windows operating systems support for clients
- E-mail server independence

Secure Unified Messaging
With Secure Unified Messaging, the voice and fax messages remain on the voice mail server, e-mail remains on the e-mail server. Using Web PhoneManager, users can access their voice and fax messages through a web browser such as Internet Explorer or Firefox. Users can access their messages through the web client, play the messages through their telephone speakers or play their messages over the telephone. For secure access, administrators can enable specific security features for specific users including using secure audio streaming to deliver the messages to the web client and restricting the ability to save a copy of the voice message on their local systems.
- Ideal for business who need to keep voice messages secure
- No local copy of voice mail
- No forwarding capability outside the company
- Web client access to voice messages
- No client install
- E-mail server independence

Simplified Unified Messaging
Copies of voice and fax messages are sent to the user at a specified e-mail address as e-mail messages with attachments, while the original messages remain on the voice and fax servers. The two copies of the messages — the one on the voice server and the one in the user's e-mail inbox — are not synchronized in any way. Therefore, each message must be deleted separately.
- Ideal for SOHO users or small business
- Works with hosted e-mail providers
- Supports any e-mail system, including IMAP4 and POP3
- Supports notification to mobile devices
