Rerouing calls dynamically to reduce the calling cost

Today in the industry most of the communication between interested parties in different geographies happens using effective communication technologies. Telephone conference is one of the most effective modes of communication to interconnect people residing in different geographies. In a situation where groups of individuals from different countries need to communicate with each other, the major problem faced is the high cost of dialing international numbers. In fact, the cost rises even if there's a huge volume of people making domestic calls to the same number, from different lines (either different lines in the office OR different lines at home). In either of the scenarios, the cost incurred is huge, both for the individuals and the enterprises.

Disclosed is an approach to reduce the overall calling cost of a group of people communicating over phone and sitting in different regions, be it within the same or a different country.

The gist of the proposal is:

1. Identifying region and country from which the user is making the call.

2. Dynamically re-route all calls made across region and country, based on the location from where the user is calling, wherein:

a. All users situated in the same region and country will join the conference via one of the target users in the same region and country to establish communication with the set of users in the other region and country.

3. All users dialing international numbers will be re-routed to local bridges created dynamically in each country from which users are calling.

4. All users dialing a common number, within the same country or region, will be re-routed to a local bridge created dynamically and ensure that a lot more participants are associated with a given line. That way the overall calling cost is reduced for a given enterprise.

The proposal is in the form of two approaches which revolves around 4 users who intend to do a conference call wherein:

1. Caller A is sitting in Region R1 and Country India.

2. Caller B is sitting in Region R2 and Country India.

3. Caller C is sitting in Region R3 and Country USA

4. Caller D is sitting in Region R4 and Country USA

Figure 1: Country specific Dynamic Bridge.

Control flow as shown in Figure 1 is to showcase how a region specific dynamic bridge helps in reducing conference calling cost:

1. Users A, B, C and D are interested in having a telephonic conference.

2. Caller A is from India and Region R1, Caller B is from India and Region R2, Caller C is from USA and Region R3 and Caller D is from USA and Region R4.

3. Caller C is the host of the meeting and its his number being used for the call.

4. The conference call is initiated by Caller C in USA, to which all other interested parties need to dial in.

5. Callers A and Caller B dial-in the international bridge.

6. Callers C and D dial in the local bridge as it's in same country.

7. Centralized telecom agency throu...
