Single Number Reach (SNR):

An SNR is a single telephone number that is used for all contact and messaging purposes. It typically combines the functions of the following:

· Work Phone

· Cell Phone

· Home Phone

· Numeric Pager

· Text Pager / Short Message Service (SMS)

· FAX

· VoiceMail

Depending on the implementation, the concepts of “Presence”, “Location”, and “Preference” are also part of the solution:

· Presence: What communication method am I able to use at the moment. (Example: Instant Messaging’s concept of “online” means the user is ready to communicate using IM at the moment.)

· Location: Where I am physically located (work, home, home office, car, customer site, travel)

· Preference: If I’m “present” to multiple communication methods, what is my preferred method (can be a prioritized list)

Cisco’s Unified Communications Solution, announced March 6, 2006, implements all of these concepts.

Example of the productivity improvement enabled by CUC:

When arriving at the office in the morning, Bob sees that Sally, Jim and Paula (all co-workers) have called.

Next to their names and numbers in his Missed Calls list are icons showing their current presence and location information.

Bob uses the presence and location information to determine the order he returns his calls as follows:

· Bob calls Paula back first, because he sees that she’s present to a landline phone and she’s at work.

· Next, he calls Sally, since she’s present to her cell phone.

· Finally he sends a message directly to Jim’s Unified Inbox, without bothering to wait for any of his phones to ring, since he sees that Jim is not present to a phone at the moment. (He can use Jim’s preference information to determine whether to send the message as voicemail or email.)
