Lync Server 2010 Has 100% Success Rate in 4 Million Call Completion Test

Microsoft’s latest unified communications solution is capable of handling in excess of 4 million calls without dropping a single one, according to the tests performed by Miercom. Earlier this week, Miercom published the detailed report with the conclusions from the Lync 2010 testing it performed, available for download here.

During no less than 13 days and 26 minutes, no less than 4,107,951 calls were attempted through Lync 2010. Miercom reveals that the success rate for Microsoft’s UC solution was 100%, with 4,107,951 completed.

“Miercom engineers decided to “bracket” a sufficient call volume that would allow for a prolonged load test and achieve at least 1 million calls running for 3 days,” reads an excerpt from the report.

“Since no calls were dropped, we continued the test to achieve over 4 million calls with 13,147 calls per hour through the Microsoft Lync 2010 Server.

“The system resources on the Lync server were analyzed to see how much of the processor capacity and memory the generated calls were using. During testing the processor on the Lync server ranged between 32% and 100% and the amount of memory used was 3.23GB out of 4GB.”

Lync 2010 manages to sustain the multi-million call volume and did so without producing any errors or dropped calls. Miercom reveals that Lync 2010 was successful in the highest capacity test applied to the Unified Communications or IP PBX products they have tested.

Rob Smithers, CEO Miercom praised Lync 2010 for the evolution that the UC solution brings to the table in a range of aspects, including performance, resiliency, and security.

“Microsoft Lync 2010 is a resilient, scalable, feature rich Unified Communications System. Microsoft Lync 2010 should be in the short list of top three to consider for enterprises communications infrastructure upgrades.

“Quality third party peripherals from Aastra, Polycom and SNOM will help Microsoft achieve more market acceptance at the Enterprise Desktop.

“Third party hardware such as the survivable branch appliance UX 2000 from NET will enable branch offices the resiliency needed for enterprise communication,” Smithers revealed.
