Definitions for use when discussing or planning a Unified Messaging Installation:
Server –
a. A computer system which provides data services to end users via their PCs, wireless
PDAs, IP phones, or other network devices.
b. A software application on such a computer system, which provides data services to
clients. For example, Vodavi’s PathFinder
IP
is comprised of many programs, including a
POP3 email server, Telnet server, Text-to-Speech engine, etc.
Client –
The PC, PDA, cell phone, or other computing device which retrieves and sends files or
messages to/from a server. Email client programs include Outlook, Eudora, Outlook Express,
Pine and many others.
Protocol –
A set of standards for exchanging signals between devices. The devices can include servers, PCs,
phones. Different protocols are used to accomplish different types of communication. Protocols
include HTTP for World Wide Web browsers, SMTP for Internet Mail, H.323 for voice over
Internet. Here is an explanation of the email protocols used for Unified Messaging:
1. POP3—Post Office Protocol 3 :
The client email program contacts the PathFinder
IP
directly, and pulls down email copies
of voice messages. Your email client, therefore, logs into more than one server—it treats
the PathFinder
IP
as an additional email account. The questions we need to answer
include: Does the client support POP3? It’s the old standard email client protocol, so
chances are very high that your client does. Is the PC/PDA or other appliance that you
are using capable of playing WAV files? Some cannot.
2. SMTP—S
imple Mail Transfer Protocol
:
The PathFinder
IP
server is configured to ‘push’ (send) an email containing a sound file
directly to your email box on your email server. An advantage here is that you continue
to just log into your PC, and when you open email your voice messages/faxes are already
there waiting for you. What we have to make sure of is this: Will the users’ email boxes
allow incoming messages from PathFinder? Often, security on the mail server is very
tight, and a rule needs to be set up to allow the PathFinder
IP
to send messages into it.
3. IMAP4—Internet Message Access Protocol version 4:
The most complicated option to set up. Similar to POP3, your email client logs into the
PathFinder
IP
as a secondary mailbox, but there is synchronization: when you delete a
message in your email box, it gets deleted on the PathFinder server as well. This also has
a disadvantage in that the user will need to manage a separate folder for voice messages
in the email box; they do not get deposited into the main Inbox. Stay away from this one
if you like to K eep I t S imple, S amuel!
Of the three protocols above, SMTP is for sending and transferring email. POP3 and IMAP4 are
for receiving and managing email. IMAP4 also offers the user the ability to store messages in
folders on the server, instead of having to download every message to the client computer and
delete from the server.
