Unique Selling Points

Hi-Interoperability with Network
IG500H has the super NAT network adaptability. In the system deployment, the remote SIP extension registered to the IG500H need not any NAT traversal setting.

Excellent Compatibility
Without NAT traversal setting, IG500H could be compliant with other mainstream SIP endpoints or components with changeable IP addresses, which effectively reduces complexity of configuration.

Intelligent Resource Allocation
IG500H optimizes system resource utilization and system efficiency via stochastic algorithm, effectively minimizing hitting over processor resource and improving reliability in any scenarios.

High User-Friendliness
IG500H leverages autoclip intelligent inbound routing mechanism. With call records, IG500H can intelligently match inbound call number with historic called one in autoclip. Moveable extension, call forwarding, DND, etc are available.

Multiple High-Security Modes
Multiple security mechanisms in IG500H are available, including password, ACL, data filtering, etc. Besides, outbound routing, DISA, conference, voice mail and other applications support PIN code setting to customize dynamic firewall.

Flexible Surveillance
IG500H adapts flexible multiple-layer monitoring modes to protect privacy at maximum level and ensure high-level of security and reliability in most conditions.
