The advent of Next Generation Networks or NGN's will foster new methods of reducing trunkline costs and eliminate or drastically reduce long distance calls. Companies will greatly benefit on the features of SIP Trunking as small ITSP's or Internet Telephony Service Providers offer innovative service offerings that can be provisioned dynamically to meet the changing needs of these companies.
The key benefits of SIP Trunking are as follows:
1. Flexible service provisioning such as "pay-per-use" service policies. No more long-term "lockouts".
2. Least-cost-routing and toll-bypass.
3. Trunk redundancy which is impossible in conventional PBX environments.
4. Single technology platform with multimedia support.
5. Simple to setup and manage compared to conventional trunklines.
IPXChange conveys SIP trunking features in a corporate environment by way of an internet or broadband network connection such as MPLS. The IPXChange Interaction Manager allows users and administrators the ability to make changes in the service policies through a web portal or desktop user-interface (UI). ICCM also offers drag-and-drop service provisioning to make it easy for user-agents or customers to acquire services without the intervention of a telco technician.
