Example - VoIP Interconnection Between AT&T and Verizon
Call Initiation
- A user on AT&T's network initiates a VoIP call to a user on Verizon's network.
Interconnect Agreement
- AT&T and Verizon have a pre-established interconnect agreement governing the terms of voice traffic exchange between their networks.
- This agreement outlines technical specifications, including the use of specific protocols and codecs, as well as business terms such as pricing, revenue sharing, and billing arrangements.
Routing and Handoff
- The call request from AT&T's user is routed through the VoIP interconnect, which determines the optimal route to reach Verizon's network.
- The interconnect manages the signaling and media streams, facilitating a seamless handoff of the call from AT&T's network to Verizon's network.
Media Conversion (if necessary)
- If AT&T and Verizon use different codecs or technologies, the VoIP interconnect may involve the use of media gateways to convert voice signals appropriately.
- This ensures that the voice data can be properly understood and transmitted between the different systems.
Quality of Service (QoS) Assurance
- Throughout the call, the VoIP interconnect maintained by AT&T and Verizon ensures high-quality communication.
- QoS mechanisms prioritize VoIP traffic, managing factors like bandwidth, latency, and packet loss to guarantee a smooth user experience.
Billing and Settlement
- As the call progresses, the interconnect handles billing and settlement processes based on the terms agreed upon in the interconnect agreement between AT&T and Verizon.
- This includes determining call charges, revenue sharing, and facilitating financial transactions between the two telecom giants.
This example illustrates how the established interconnect between AT&T and Verizon works, Thus allowing users on their respective networks to seamlessly communicate through VoIP technology.
The interconnect plays a crucial role in managing technical aspects, ensuring quality, and facilitating the business aspects of voice traffic exchange between these two major telecom providers in the USA.
I'm sure this example sheds a brighter light on the workings of a VoIP Interconnect. With all the basics covered, we can get to the main point.
How to Establish a VoIP Carrier Interconnect?
As with every important business process, there are several steps involved in establishing a VoIP Interconnect with another carrier. Here's a general outline of the process:
