This makes ETERNITY a truly ‘Universal Communication Platform’ and offers flexibility to users to avail specific advantage offered by each of these network.

Dynamic DNS (DDNS)
Matrix ETERNITY VoIP SERV+TRK card supports Dynamic DNS client which automates the discovery and registration of IP addresses on the public network. The remote administrator and the IP clients can always connect to the ETERNITY using Domain Name associated with the dynamic IP, preventing reconfiguring of systems each time a network infrastructure changes.

Matrix ETERNITY IP-PBX can register as many as 999 IP users to VoIP SERV+TRK card. ETERNITY offers complete resiliency while registering IP users with the VoIP SERV+TRK card. The IP user can be registered to the VoIP SERV+TRK card or shared between the multiple VoIP SERV+TRK card, installed on the same ETERNITY platform. It employs licensed architecture as per number of user registrations.

Number of VoIP Calls
Matrix ETERNITY PE VoIP SERV+TRK card supports 4, ETERNITY GE supports 16 and ETERNITY ME VoIP SERV+TRK card supports 32 calls at a time. With Universal Slot Architecture, the VoIP SERV+TRK card can be scaled in equivalence to the maximum number of slots available with ETERNTIY IP-PBX variants.

NAT and STUN Support
NAT allows multiple devices in a LAN to share a single public IP address and automatically creates a firewall between the internal network and the Internet. The STUN client allows an IP terminal located behind a Network Address Translator (NAT) to obtain the mapped (public) IP address (NAT address) and port number that the NAT has allocated for connections to a remote host. SIP clients can thereby easily register to the IP SERV hidden behind the NAT router and corporate Firewalls. The STUN support is critical to establish a VoIP call between SIP clients located behind different type of NATs.

Registrar server
When a SIP user comes online, they get registered to the embedded registrar server of the VoIP SERV+TRK card. The registrar authenticates a user and maintains mapping of their current and active IP addresses mapped to a user’s SIP URL.

VoIP Silence Disconnect Timer
It defines the time limit after which calls are disconnected, if no voice packets are received from the SIP clients on the IP Network leads to better bandwidth resources utilization.

GSM/3G Connectivity
Matrix ETERNITY IP-PBX supports Mobile connectivity through an optional card and each card offers 2, 4 or 8 SIMs (ports) with dedicated SIM on each port. The use of particular frequency band is software selectable. The default band is 900+1800 MHz.
