Convergence Practice
Convergence practice within GS Lab works for customers with modern as well as legacy telecom and datacom products and services. The practice has been working on large scale telecom core infrastructure products, enterprise products as well as on end-user communication products.
We have worked on peer-to-peer VOIP appliances as well as on core network products. Scale of problems within field of carrier-grade communication is huge and reliability and scalability of the solution plays the most important role while selecting a solution. GS Lab has developed large scale solutions for its customers and has also maintained deployments for these products.
The various categories of macro functionality listed in each block of the diagram below represent the expertise and successful track record of delivery by GS Lab.

Differentiation
With expertise in career grade solutions and experience with enterprise as well as value added service market, GS Lab is the most sought after partner for convergence companies looking to reduce their development and testing time. GS Lab’s emphasis on quality of delivery and efficient communication complements the domain expertise.
Communication solutions require ability to design distributed reliable and scalable solutions that conform to specifications by various standards committees and organizations. GS Lab has experience with country-specific certifications for telecom products that is important for communications products since they must interoperate.
GS Lab’s expertise in development, testing and maintenance of different type of convergence applications and appliances has been useful for our customers in conceptualizing new services, improving and revamping their existing design as well as adding new features and functionality to their existing products.
Some of the current work in progress
Development of a system monitoring tool set for operator deployments of a soft switch
Directory-enabled management of an enterprise-grade IP-PBX
Real-time collaboration services for enterprise collaboration
A consumer-oriented telecom 2.0 voice-based social networking
Testing of a heterogeneous VoIP and PSTN deployment
Delivery capabilities
GS Lab has helped conceptualize new tools and enhancements for existing products. For example, for a client providing management software for a leading enterprise communication product. Given our keen understanding of telecom statistics, a desktop based monitoring and statistics application was introduced and it has received widespread accolades from the administrators and users for the enterprise communication software.
With another customer GS Lab’s experts have developed delivered the next generation distributed architecture based on SIGTRAN. This helped our customer deploy geographically distributed and redundant network elements and also reduce the deployment cost by eliminating costly legacy media by IP based infrastructure.
