Meets FCC part 68 protection requirements
A stateful packet inspection firewall is used in combination with a VoIP
application layer gateway to provide comprehensive "media-aware" security.
The 4350 also supports IPSec for secure site-to-site networking.
The 4350 resolves NAT/FW traversal problems for SIP, MGCP and H.323
traffic. It allows a single public IP address to be used for multiple VoIP clients.
The 4350 maximizes WAN link utilization while optimizing voice quality
using prioritization and shaping.
Passive call quality monitoring for each SIP or MGCP voice call includes
statistics needed to enforce SLAs and resolve networking problems that
negatively affect call quality.
The 4350 is a powerful, flexible platform that can be deployed initially as a
low-cost WAN access router and then licensed through software for more
advanced VoIP features and increased call performance. It is the ideal
platform for service providers offering DIA, hosted VoIP and managed
security services or enterprises migrating to converged voice and data
networks.
