The H.323 compatibility helps VIP-400/400FS/400FO cooperate with any popular H.323 applications or gateways in the marketing like Windows NetMeetings, WebPhone, etc. While ITU G.711, G.723, G.726 and G.729 voice CODEC and compression also helps it to compatible with the world-famous Internet Telephony System like Cisco, RADVision, etc. Furthermore, VIP-400/400FS/400FO are now able to support DDNS service, which brings great convenience to establish voice communications in a dynamic IP environment. Collaborate connection agents (PPPoE, or DHCP clients), VIP series built-in DDNS client can help those who don't have static IP address to map dynamic IP address to an easy-to-remember URL, and this will allows other 3rd party voice gateways to connect to VIP much easier than ever.

Key Features
Standards compliant & Surpassing voice quality
- PLANET VIP-400/400FS/400FO are H.323 standard version 3 compliant (including H.323 faststart mode). VIP-400/400FS/400FO are interoperable with 3rd party voice gateways as well as other PLANET VoIP products. Retaining excellent traditions in PLANET VoIP products, VIP-400 prioritizes voice packets using IP precedence, and combine state-of-the-art technology of voice packet handling, including echo, noise reduction, voice reconstruction and redundancy to provide customers toll quality VoIP communication.

VoIP, FoIP and Network conversion
- Via configurable voice codec: G.723, G.729ab, G.711mu and FAX: T.30, T.38, VIP-400 supports for multiple algorithms to meet different VoIP application demands. VIP-400 support converting telephony protocols (SS7, Analog (FXS/FXO)) into packet switching network between calling and called voice gateways or PBX system, in a heterogeneous signal-switching environment.

Domain name call & DDNS supports
- Either IP or URL addressing, VIP-400/400FS/400FO are able to find, and communicate with destination H.323 gateway/terminal. Meanwhile, DDNS service is very useful to those VoIP gateways deployed in a dynamic IP environment. Collaborate connection agents (PPPoE, or DHCP clients), built-in DDNS client in VIP-400 can help those who don't have static IP address to map dynamic IP address to an easy-to-remember URL, and this will allows other 3rd party voice gateways/terminal to allocate position of VIP much easier than ever. (To establish voice communication via domain name, please make sure the other party gateway/terminal supports domain name call.)
