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.

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
