Video Gateway

Wifi’s Video Gateway offers carrier-grade seamless telephony and streaming connectivity for video and voice between 3G-324M-enabled mobile devices and IP/IMS-based services. Our 3G Video Gateway connects mobile networks and IP networks – where multimedia content and current video telephony systems reside. Wifi’s 3G Video Gateway supports real-time bi-directional video and voice telephony and streaming between 3G-324M-based mobile handsets or devices and IP-based video media servers, messaging systems, RTSP streaming servers, SIP/H.323 terminals, network cameras, ISDN endpoints and more.

AAC

SIP Server High-Availability and Redundancy:

SIP Server keep alive mechanism - automatically identify faults
and failover between SIP servers with a standard based bidirectional
keep-alive mechanism
Highly redundant solution with N+1 or N+N redundancy of the
RAI/RAC Load Balancing - Resource Available Indication/Resource
Available Confirmation function on H.323 networks

Security:

Management and media traffic separation
Configurable management access control lists
Secured management Web access
Strong password enforcement
Previous passwords tracking
Session inactivity timeout

Quality of Service (QoS):

Configurable IP TOS bits for setting any desired IP class of service or DiffServ Code Point (DSCP)

Smart Dial Plans:

Calls originating on 3G-324M can be routed, in addition to Direct Inward Dialing (DID) methods, with the following unique methods:
Video-to-Voice Failover - automatic failover of IP originated
calls from video call to voice TDM call based on media type not supported
E-mail addressing - dialing from the handset an email address/SIP
URI Instead of a number
Sub-addressing (Q.932 IE) - sending from the handset both the
access number as well as the destination number

Centralized Element Management:

Easy and intuitive control, configuration, and maintenance of VAS from a single User Interface, including:

Complete network-wide view of element status
Forward SNMP traps from all components to designated third
party management systems
Display of events and errors received from elements for error management
Multiple element configuration management, multiple element software upgrade capabilities

RTSP Interface:

Seamless connectivity between RTSP streaming servers and
Web cameras
ISMA implementation specification v1.0, profile 0
3GPP TS26.233 (version 5.0.0) and TS.26.234 (version 5.4.0).
RFC 2326.

SS7 Signaling:

Market-proven SS7G21 signaling gateway for complete ISUP support
Single access point to the circuit-switched network, supporting up to 2,000 calls
Standards-based redundant solution
Supports International and Local Protocols in Variants
