Any call type including PSTN/Voice Calls

• H.323 Fast Connect enables endpoints which
  support the feature to join a voice conference in
  the Gateway more quickly
• Line echo cancellation for maintaining high
  quality voice
• DTMF detection

11
Any media - Dual Video (H.239 / Duo Video)

• Support for H.239 as well as Duo video for rich
  media calls
• Dual video streams enable simultaneous
  transmission of two separate streams, one for
  video and another for data

Scalable and fault tolerant
13
Scalable and fault tolerant

• Distributed architecture
• No single point of failure ? high service
  availability
• Supports least cost routing ? saves money
• Enables ISDN-based multi-site architecture
• Optimal utilization of available resources and
  services
• ISDN rollover
• ISDN fallback
• load balancing using H.323 RAI/RAC

14
Load Balancing over the IP network

• Balance among multiple gateways with a
  centralized gatekeeper supporting H.323 RAI/RAC
• Smart resource management on the network
• Enables the reservation of resources for incoming
  ISDN calls

Load Balancing over the ISDN Network

• Load balancing for T1 PRI lines among multiple
  gateways
• The ISDN/PSTN switch rolls over to another
  Gateway when the gateway capacity reaches a set
  limit
• Enables the reservation of resources for incoming
  IP calls

Automatic ISDN Pending Registration

• Automatic un-registration of gateway from
  gatekeeper during ISDN network problems
• Re-registration with gatekeeper upon recovery of
  ISDN connectivity
• Prevents a Gatekeeper from attempting call
  settings via a gateway when both of its PRI ports
  are down
• ? High call succession rate

17
ISDN Fallback

• Support for automatic fallback from IP to ISDN
  when lacking bandwidth to set up a call over the
  IP
• Requires ECS v3.5 and up

  utilization indications, traps
• Password protected access

21
Easy to use flexible dialing

• Inbound Dialing (ISDN ? IP), one of the
  following
• Direct Inward Dialing
• IP endpoint defined per ISDN number dialed
• Q.931 sub-addressing
• Integrated IVR
• TCS4
• Default extension
• Outbound Dialing (IP ? ISDN),
• Simplified outbound dial plan using a single
  universal prefix
