VoIP

Voice over IP is becoming widespread in the business world, introducing new functions and cutting costs compared to the traditional solutions they replace. To ensure connectivity and uptime for this critical business asset, IT managers must proactively plan for outage contingencies.

The Elfiq Link Balancer is a great choice for achieving this objective. The ability to use multiple IP links of any type concurrently will make failures due to WAN link outages a thing of the past. A sound strategy to maximize uptime and availability is to use at least two links from different providers and different technologies managed by an Elfiq Link Balancer.

Elfiq’s Link Balancer products are SIP-Aware, ensuring SIP trunks can be failed over to an alternative ISP link dynamically without IT staff intervention. This feature enables maximum uptime for such deployments.

In multisite VoIP implementations over private WAN links, Elfiq’s advanced WAN load balancing provides site-to-site link resilience. This allows load balancing and failover between multiple site-to-site WAN links and the use of QoS markings to ensure the quality of VoIP communications.

Additionally, in multisite VoIP implementations over VPN tunnels, Elfiq’s SitePathMTPX technology provides point to point link resilience. Should a link fail, the VPN connection between two sites will remain active over the remaining links, and communications will not be interrupted.

Feature	Description	Benefits
Core Technologies	Enable use of multiple ISP links	Provides a redundant telecom infrastructure More ISP links add more performance for WAN-based services Enables bandwidth provider diversification to prevent downtime
SIP-Awareness	Brings resilient VoIP communications	Enables VoIP communications to operate even if an ISP for the SIP trunks fails
iDNS	Balance inbound traffic	Proactively distribute traffic for remote users and applications Provide failover capacity for remote users and applications such
Intelligent Service Verificator	Proactively distribute traffic to best available servers	Ensures data requests are sent to servers operating normally Prevents requests from being sent to slow or inactive servers
Intelligent Condition Verificator	Enables complex confition-based configuration	Existing configurations can be dynamically adjusted based on selected criteria Common usage inclues usage of links based on cost, altering priorities based on link comditions or failure and statistics reset
LAN Failsafe	Continues operations with 1 ISP if the unit loses power	Even if the Elfiq unit is physically powered off, VoIP servers will continue operating
High Availability	Redundant unit management	Enables maximum uptime for bandwidth availability for VoIP environments
QoS and Traffic Segmentation	Bandwidth allocation management	Ensures that each VoiP server or service has the required bandwidth to deliver its value to users on specific links Prevents low-priority traffic from using key bandwidth resources
SitePathMTPX	Point to point resilience and performance	Increases performance of site to site Fault-tolerance for VPN or VoIP deployments.  Should one ISP fail others will keep the VPN or VoIP tunnels functioning normally Optional AES128 encryption can add an extra layer of security
