H.323 Version 2). The fourth version of the H.323 standard improves
system resource usage (esp. logical port or socket usage) by handling
call signaling more compactly and allowing use of the low-overhead
UDP protocol instead of the error-correcting TCP protocol where
possible.
The MultiVOIP is also SIP-compatible. However, H.450
Supplementary Services features can be used under H.323 only and not
under SIP.
The MultiVOIP3010 comes equipped with a variety of data
compression capabilities, including G.723, G.729, and G.711 and
features DiffServ quality-of-service (QoS) capabilities.
VOIP Functions. The MultiVOIP MVP3010 gateway performs four
basic functions: (a) it converts a dialed number into an IP address, (b) it
sends voice over the data network, (c) it establishes a connection with
another VOIP gateway at a remote site, and (d) it receives voice over
the data network. Voice is handled as IP packets with a variety of
compression options. Each E1 connection to the MultiVOIP provides 30
time-slot channels to connect to the telco or to serve phone or fax
stations connected to a PBX.
Ports. The MVP3010 also has a 10/100 Mbps Ethernet LAN interface,
and a Command port for configuration. An MVP3010 upgraded with
the MVP30-60 kit will have two Ethernet LAN interfaces and two
Command ports.
Management. Configuration and system management can be done
locally with the MultiVOIP configuration software. After an IP address
has been assigned locally, other configuration can be done remotely
using the MultiVOIP web browser GUI. Remote system management
can be done with the MultiVoipManager SNMP software or via the
MultiVOIP web browser GUI. All of these control software packages
are included on the Product CD.
