Cisco Unified Mobility: Single Number Reach & Call flows





This document describes the basics of Cisco Unified Mobility, Single Number Reach & the Call flows. This will help the beginners to understand the basic call flow and the working concepts of Cisco Mobile Connect.


Cisco Unified Mobility allows users to be reachable at a single number, regardless of the device they use. The growing use of mobile devices allows users - whether on a retail floor, at an airport or at Wi-Fi hotspot in a local coffee shop- to enjoy the features, efficiencies and speed of Cisco unified communications.


Cisco Mobile Connect: Allows an incoming call to the enterprise phone number of a user to be offered to the office phone of the user. The call can also be offered to as many as ten configurable remote destinations. Such remote destinations typically are mobile or cellular telephones and home-office phones. This feature is commonly referred to as Single Number Reach in traditional telephony environments.



Cisco Mobile Connect: Call flows


1. Incoming Call from a PSTN Network to Mobile Connect - Remote Phone


Mobile Connect enables users to receive business calls at a single phone number, regardless of the device that is used to receive the call. Mobile Connect allows users to answer incoming calls on the office phone or at a remote destination and pick up in-progress calls on the office phone or remote destination, without losing the connection.


Below figure illustrates the call flow when Mobile Connect is used. The figure shows an IP phone with extension 2001 and a mobile phone that belongs to the user of the IP Phone.

In this example, a PSTN user calls the office number of the user. Because Mobile connect is enabled, both the desktop phone 2001 and the configured remote destination (mobile phone 408 555-1001) ring simultaneously. The call is presented to the remote phone with the original caller Id (479 555-1555). As soon as the call is accepted on one of the phones, the other phone stops ringing. The user can switch the call between the office phone and the mobile phone (and vice versa) during the call, without losing the connection.



2. Internal Calls Placed from Remote Phone


Mobile Connect influences the calling-number presentation. If a call is received from a recognized remote destination, the corresponding internal directory number, not the E.164 number of the remote device, is used as the calling number.


This figure illustrates, extension 2001 has a Mobile Connect remote destination of 408 555-1001 (Cell phone of the user of 2001). The user places a call from the mobile phone to an enterprise PSTN number by dialing 1 511 555-2002. The called number sees the call as coming from the internal directory number 2001 instead of the external mobile phone number.


Hence, the Internal Call Placed from Remote Phone 2001 is terminated to the Internal office desk Phone extension 2002.





The same applies to calls that are placed to other internal destinations, such as voicemail.
