Voice over IP (VoIP) Enhancements

Dedicated Physical Ethernet Ports for Subnet Addresses on Matrix I/O

This feature uses the second Ethernet port on the Matrix Controller I/O card to segregate switch control traffic and SIP signaling traffic on different physical interfaces. The feature allows the host and Matrix Port A to be on a private, isolated LAN, while the SIP signaling, using Matrix Port B, can be connected (likely through a firewall) to a different LAN or even to the public Internet. This separation reduces the exposure of the Matrix control and hosts to Public Networks and to potential Denial of Service attacks.

Scaleable IP Network Interface Series 2 Card Available in Single and Dual Module Options

Excel now offers the IP Network Interface Series 2 (IPN-2) card in Single and Dual Module options. Because you pay for only the number of resources you require, these options make the card more cost effective at lower densities, and allow customers flexibility and cost effective redundancy at higher densities. You can purchase the IPN-2 card in the following options:

• IP Network Interface Series 2 with One Module – 96 ports that are upgradeable to 265/512 ports (depending on codecs)

• IP Network Interface Series 2 with Two Modules – 192 ports that are upgradeable to 512/1,024 ports (depending on codecs)

• Additional IP ports license are in in 96 port increments
