| Features |
1. Supports both H.323 and SIP protocols: H.323 Gatekeeper Registration, SIP Registration, and Digest Authentication
2. Flash Time Programmable: Gateway support Flash detection and generation to switch VoIP Call
3. Caller ID Delivery and Detection: support DTMF & FSK Caller ID generation
4. Smart VoIP Call Dialing Book
5. Polarity Reversal Detection: Type I and II
6. Pass NAT: allow Gateway to operate behind any NAT/Firewall device. There is no need to change any configuration of NAT/Firewall like setting virtual server
