IP Trunking |
13.7.1 |
Overview |
|
|
| The implementation of IP telephony between the HiPath 3000/5000 communications platforms has several advantages for our customers such as saving on expensive leased lines for telephony only, the convergence of communications networks for voice and data over several locations, a standard contact partner for the infrastructure and other advantages. |
| The main advantage for users of IP telephony is a significant saving on costs by using a single infrastructure for data and voice. This advantage can be even further expanded by using the voice compression procedure, Compression enables existing lines to be used much more effectively. For example, up to three calls can be conducted simultaneously on a single ISDN channel if an optimized compression algorithm is used. A considerable reduction in costs can be expected particularly for companies that already have a broad-band intranet. IP trunking is available over the integrated ISDN router HG 1500 voice/data (Hicom Xpress@ LAN Data/Voice). |
