About Converged Communication Systems

Business phone and contact center systems are designed, deployed and supported by Converged Communication Systems, LLC, an Avaya business partner that works with clients of every size in many countries. The company was founded in 2003 by two telecommunications professionals who felt that too few Avaya partners gave careful, service-first support. It describes its approach as consultative, and says that its portfolio includes several brands so that it can recommend the right product for each client rather than sell a single one.

Phone systems, maintenance and managed telephony

Its implementation work covers Avaya and cloud deployments, with project management, and it offers global Avaya engineering services. For existing installations it provides phone system maintenance and managed telephony, which keeps systems running and supported. It also works on video, conferencing and desktop collaboration tools, whether on premises or in the cloud, and on advanced applications such as mobility, instant messaging and remote working.

Cloud calling and contact centers

For cloud communication, the company offers unified communications as a service and cloud phone systems, including Avaya Cloud Office by RingCentral. Its contact center offer covers contact center as a service and outsourced call center operations, known as business process outsourcing. The company says it can migrate clients from an on-premises phone system to a cloud solution, and it positions its consultants as neutral advisers who compare options across brands.

Network and infrastructure for voice

Beyond phones, the company supplies routers, firewalls and managed switches, and it arranges network services such as T1 lines, MPLS, metro Ethernet, fiber and SIP connections. It designs VoIP networks spanning several sites, and it supplies IP telephony to people working from home. The company's view is that clients are served best by an approach that puts service ahead of sales, and that long relationships are built on doing the difficult service work well.
