RADIUS Support. Inter-operation with a RADIUS server allows for
call accounting (especially for billing) on a voip system. The MultiVOIP
supports inter-operation with RADIUS servers for the RADIUS
accounting function (but not the RADIUS authentication function).
STUN Support. The STUN protocol (Simple Traversal of UDP through
NATs (Network Address Translation)) assists with the packet routing
functions of devices behind NAT firewalls or routers. The MultiVOIP
supports inter-operation with STUN servers and NATs (SIP based
environment only).
Gatekeeper. T1 voip systems can have gatekeeper functionality by
adding, as an endpoint, a Multi-Tech standalone gatekeeper (special
software residing in separate hardware). Gatekeepers are optional but
useful within voip systems. The gatekeeper acts as the ‘clearinghouse’
for all calls within its zone. MultiTech’s stand-alone gatekeeper
software performs all of the standard gatekeepers functions (address
translation, admission control, and bandwidth control) and also
supports many valuable optional functions (call control signaling, call
authorization, bandwidth management, and call management).
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.
