Communication as a Service (CaaS)

The CaaS model allows business customers to selectively deploy 
communications and services based on pay-as-you-go basis for the services they 
use. CaaS is designed around a general purpose pricing policy that provides users 
with a comprehensive, flexible, and easy-to-understand service plan. According 
to Gartner, the CaaS market is expected to be worth $2.3 billion in 2011, with an 
annual growth rate of over 105%. 
CaaS service offerings are often bundled and include integrated access to 
traditional voice (or VoIP) and data, additional unified communications 
functionality such as video calling, collaboration, conversations, real-time 
presence and messaging, telephony, local and distributed voice services , voice 
mail. The CaaS solution includes redundant switching, networking, hardware 
redundancy, WAN failover - which definitely suits the needs of the customers. 
All VoIP transport components are located in geographically distributed, secure 
data centers for high availability and survivability. CaaS provides flexibility and 
scalability for small and medium-sized businesses, which companies often cannot 
provide on their own. CaaS service providers are prepared for peak loads, provide 
services to expand the capacity of devices, states or area of coverage at the request 
of the customer. Network bandwidth and feature sets can be changed dynamically 
so functionality keeps pace with customer demand and vendor-owned resources 
are not wasted. Unlike the service provider, the customer's perspective does not 
actually lead to the risk of maintaining outdated equipment, as the CaaS service 
provider's obligation is to periodically upgrade or replace hardware and software 
to keep the platform technologically up to date. CaaS does not require control 
from clients. This eliminates the need for customers to make any capital 
investment in the infrastructure, and it eliminates the overhead for the 
infrastructure. With a CaaS solution, customers are able to leverage enterprise-
class communications services without having to build their own solution within 
their organization. This allows clients to redistribute the budget and labor costs 
of the staff, to use them in those places where it is most needed.From the handset 
that can be found on every employee's desk to the client software on the 
employee's laptop, VoIP is privately based, and all necessary actions between 
each of the components in the CaaS solution are supported 27/7 by the CaaS 
service provider. - Placement and management solutions. 
Remote management of infrastructure services provided by third parties 
seemed to be an unacceptable situation for most companies. However, over the 
past decade, with advances in technology, networking and software, the attitude 
has changed. This is partly due to cost reductions in the use of selected services. 
However, unlike a single service offering, CaaS service providers provide a 
complete communications solution that is fully managed by a single vendor. 

Along with features such as VoIP and Unified Communications, PBX integration 
with additional functionality is managed by a single vendor who is responsible 
for all integration and service delivery to users.
