Configuring VoIP
The following example of a VoIP network features INDeX to INDeX as well as a Home Office / Small Office. This allows VoIP calls to support 'user to user' features that are normally specific to DPNSS.

INDeX to INDeX VoIP Trunking
The INDeX IP Networking cassette (IPNC) allows the use of the data Wide Area Network to make desk to desk voice calls between INDeX's. Since leased lines typically have a fixed cost, voice traffic essentially travels for free, courtesy of the data infrastructure. The IPNC uses voice compression technology to make the most of available network capacity. Using industry standard compression (G. 723.1 and G.729a ) up to 20 voice calls can be made simultaneously.
Recent releases of INDeX software introduce the ability to packetise our DPNSS and
This positions INDeX in a very strong networking position with the ability to network over traditional private voice circuits, dial up, ISDN circuits and now IP circuits.
VoIP can be implemented either by connecting the leased line directly to the INDeX, or by using existing leased line routers. Connecting the leased line directly to the INDeX is the simplest and most secure solution - the IPNC takes IP data from the LAN and combines it with INDeX voice traffic for delivery over the leased line. Each leased line can operate at speeds of up to 2Mbps.
