VoIP Carriers : Replacement for Traditional Connectivity

By: Kristen

The VoIP carriers have become an ultimate means of achieving connectivity or terminating calls with ease. This works well as the carriers have merged their services with other higher version network providers. This has, in a way, resolved the issue of fast connectivity at low rates for many users - business or otherwise.

In general, the VoIP carriers offer their services to the resellers. The system follows a three tier rule. Tier 1 carriers offer their services to Tier 2 that in turn enables the functioning of Tier 3. The Tire 1 consists of those companies that come with their physical network either in one country or in some regions of the world. The carriers at this level can terminate the voice traffic or can carry forward a call using their own equipment and expertise. The second is the Tier 2 that consists of companies that take the network of Tier1 on leases it in order to terminate international calls. The Tier 3 consists of service providers that make use of Tier 2 or Tier 1 carriers to terminate international calls.

With the introduction of VoIP, several technologies have converged so as to enable a more reliable and sophisticated service in the realms of communication. The convergence of the Internet with other allied networks has led to the generation of an infrastructure that supports the carriers and suppliers of IP telephony services more comprehensively. As there are several suppliers of origination services, so now the VoIP carriers prefer to have connections that give them the flexibility to switch to different origination services as and when the need arises.

This new capability in VoIP carrier service is achieved by a Session Internet Protocol (SIP) that is actually another interconnection. This connection provides unique efficiencies in networking and also maintains flexibility in its design so as to cater to the needs of different categories of carrier customers. Though SIP allows the customer to switch to different origination services but it is actually based on inbound and outbound call service. That is to say that once an inbound call is received, the customers can use the 'Global Crossing Carrier' or outbound service to send the call back to its destination. So, for a VoIP service provider, SIP is used as a gateway for telephony, internet conferencing, events notification and instant messaging.

The VoIP carrier service is not just restricted to the use of telephone connections and computers. There is more than one way of assessing these services. Quite a few carriers have expanded their services to mobile phones as well. The Wi-Fi technology has enabled receiving of voice over IP services in mobile phones. In fact, the fixed wire-line service providers are facing stringent competition from the mobile "Voice over IP" service providers. In case of mobile, the technology works well if the location where it is installed is Wi-Fi enabled. However, a location can be converted to Wi-Fi so as to access such a service. So, now offices, homes and college campuses can easily be converted so as to allow every mobile user to access voice over IP services. In case of mobiles, the mobile service providers have to collaborate with other VoIP carrier service providers. This would help avoid any controversies.
