IP Exchange lines Still in the production pipeline, the closest technology to this currently is PADSL .IP Exchange Lines are a service that will deliver IP connectivity from a company's internal voice over IP (VoIP) system to the Public Switched Telephone Network (PSTN). The service will provide new enhanced external communications capabilities to businesses, as well as greater network scalability and a reduction in expenditure on hardware and calls. Connectivity to the PSTN from a company's voice network has traditionally been through analogue or ISDN channels. However, as more and more businesses move to converged IP networks, demand for connections through IP to the PSTN has increased. By integrating IP Exchange Lines with a VoIP solution, external voice calls can be delivered across IP to the PSTN, reducing the amount of hardware an organisation has to deploy. Companies deploying IP Exchange Lines as part of their IP telephony roll-out will receive significant benefits. Research reveals that the technology will decrease the number of lines required to connect to the PSTN by up to 30%, cutting line rental costs and expenditure on hardware such as IP-PSTN gateways. Considerable savings can also be made on call rates and businesses will gain greater control and flexibility on where calls are routed, meaning they can send calls to employees direct dial numbers (DDI), regardless of their location, without first routing them to the original site of the DDI. Additionally, IP Exchange Lines will provide greater scalability and faster network upgrades as well as enabling soft upgrades to be administered remotely. Other standard features of IP Exchange Lines will include DDI, existing number portability, call barring and call divert services. |
