User Guide V2IU 4300T Converged Network Appliance

Although RTP makes use of UDP the 4300T appliance is able to provide its own congestion avoidance mechanism for voice traffic using Call Admission Control (CAC).

VoIP Survivability Configuration

The high availability of voice services is a fundamental requirement for enterprises deploying their own IP telephony equipment or subscribing to hosted VoIP services. In both cases providing reliable communications to remote branch offices is costly usually involving the installation of local call processing servers or additional wide area network (WAN) links to these locations.

Polycom’s VoIP survivability enhances the reliability of VoIP services to branch offices in a cost effective manner by providing local call switching in the event of WAN link failures or a loss of connectivity to network based call processing servers. VoIP survivability is an orderable software option for Polycom’s V2IU Series appliances. V2IU appliances are flexible networking devices that can also be configured to provide IP routing, optional T1 WAN link termination, resolve NAT/firewall traversal problems, ensure high quality voice using QoS, monitor voice call quality and provide comprehensive security for the LAN using a VoIP and data firewall.

Key benefits and features of VoIP survivability

Polycom’s VoIP survivability offers the following important benefits:

Continuity of voice services to branch offices during WAN link failures or failures in network based call processing servers

Significant savings over alternative solutions requiring redundant call processing servers or multiple WAN links

Simplified design that is easier to manage than alternative solutions requiring maintenance of multiple dial plans in distributed call processing servers and complex routing
