Telecommunications Solutions Brief
Competition for subscriber communication and entertainment dollars is heating up even as
carriers and service providers are struggling to maintain margins. The high penetration rate of
broadband Internet access coupled with the wide acceptance of industry-standard IP components
has opened the door to a diverse mix of competitors seeking additional revenue opportunities.
Without the need to build an expensive access network, the barrier to entry for delivering
residential voice services has been lowered, and the market for Voice over IP (VoIP) service
offerings is crowded with traditional telco providers, wireless, broadband, and next-generation
Many incumbent telecommunications operators are offering VoIP services as a cost-effective way
to capture additional subscriber revenues while protecting market share for their existing service
offerings. By bundling residential VoIP services with video and data, these service providers can
deliver added value to customers in the form of consolidated billing, Web-based self-management
of CLASS features and enhanced services, such as click-to-dial and unified messaging.
Competitive pricing and superior mobility continue to help wireless operators gain market share
over traditional operators. To further extend their market reach and revenue potential, wireless
operators can offer seamless handover between wireless and IP-based networks. This improves
in-home coverage and allows bundling of data and voice service within WiFi hotspots or
Broadband service providers (MSOs or ISPs) can add value and increase market share by adding
VoIP as an overlay to their existing networks. Their ability to deliver end-to-end Quality of
Service (QoS) coupled with their understanding of data security gives these providers a
competitive edge. The enhanced services capabilities of VoIP can also enable these providers to
differentiate their service bundles from those of traditional telco competitors.
Greenfield service providers can deploy VoIP via the public Internet or managed IP networks to
create free or low-cost alternatives for voice and video communications services. For example,
companies can offer free instant messaging (IM), voice and video communications to drive
advertising revenue from a search engine, on-line retail site or social networking service. These
providers are creating new competition, especially for international long distance services.
In an extremely complex and competitive marketplace in which new players are usurping the
domain of the traditional telco, future success will be awarded to customer-focused, innovative
service providers. Assuming a proactive strategy by expanding service offerings to include high-
speed Internet access and VoIP services along with broadcast video and wireless services can be
the key to protecting an existing subscriber base and maximizing revenue opportunities.
The communications and entertainment market are quickly converging and subscribers are
responding to value-added services that help optimize their time and budget. Bundling voice, data
and video services has emerged as a clearly successful trend for attracting and retaining
customers while increasing revenue. To profit from this opportunity, service providers must
evolve their networks — while rigorously managing expenses — so that they are capable of
introducing value-added differentiated services to the market quickly in response to changing
customer needs. Stratus Telecom offers service providers a complete solution and roadmap to
help evolve their networks at their own pace while integrating VoIP services into any network:
PSTN, wireless, cable, or next generation carrier network.
