SARK UCS is a new kind of PBX platform, built to cope with medium to high workloads on existing copper and fibre-based TDM networks. It is equally at home in the 21CN world of SIP and VoIP. Designed and developed for the UK market by UK telephony people, the platform is reliable, fast and has a low cost-of-ownership when compared with traditional TDM and proprietary IP offerings.

SARK UCS also has many unique features which give it a substantial edge over its competitors, particularly in the areas of high-availability and remote platform support. Issues that are of particular importance to those users whose businesses depend upon high levels of customer interaction and care.

Switching Performance

SARK UCS uses its own on-board high-speed logic and rules engine (the HSLE). The HSLE is very small and fast, being optimised to switch high volumes of in-bound and out-bound calls in the minimum number of cycles. The end result is much faster switching decisions from SARK when compared to its competitors. Thanks to HSLE, SARK UCS can comfortably sustain high call arrival rates on relatively low CPU power, making it ideal for deployment into high volume or high “spike” environments.

''FlatPack'' Turn-Key Solution for Fast and Easy Deployment

With the VoIPVn developed configurator documentation, VoIPVn resellers can forward order PBX systems with all key provisioning and routing information pre-loaded. This combined with the PBX’s autoprovisioning software (available for most popular SIP phone types) means installation and deployment is painless, error free and normally completed in just a few hours.

Remote Support / Management

VoIPVn systems have been developed with the most advanced remote management, configuration and diagnostic capabilities of any PBX in their class. Tools like the unique SIP Dynamic Proxy capability plus automatic recognition and adoption of new SIP devices, enable effective system and terminal management, and make on-going adds, moves and changes much easier for both customer and supplier

Reliability – High Availability (HA)

Where high levels of reliability and uptime are of the utmost importance, as for example in call centre applications, the VoIPVn SARK advanced High Availability option can be of huge business value. The HA cluster comprises two PBX servers with identical configurations running side by side and connected by a ''heart beat'' mechanism. In the event of a failure of the primary system, fail-over to the secondary takes just a few seconds and requires no reprogramming or restart of either the phones, the VoIP accounts, gateways or ISDN circuits. The total downtime in such situations is usually around 12 to 20 seconds from initial failure to resumption of operations. When compared to the minimum 4 hour callout, or next business day support terms available from our competitors, this one feature alone can make a huge difference to the bottom line in call-critical businesses.
