Fixe mobile convergence for Business Centrex

The Uniquity Centrex application provides a fixed mobile convergence service to allow Uniquity centrex end-users to access to their services and be reachable, from a regular SIP phone and from a mobile phone as well. In this case, the Uniquity Centrex application manages users that are declared with a regular fixed phone number for their IP phone, and a mobile phone number as an external account number.

The advantage is that the end-users, the persons calling or called by the Uniquity centrex user only type or see the company extensions.

The requirement on the mobile network is to route calls from the mobile to the ACS platform, based on a defined prefix (i.e. #88) dialed by the end user.

The mechanism implemented by the ACS relies on:

1. linking to the same account the company extension number and a mobile phone number
2. providing the flexible SIP from and to header manipulation and routing, based on the end-user profile.
