Are we there yet? Assessment & Perspective
The vicious circle of innovating from within
a big incumbent, macro & micro perspective
CPaaS: Communications Platform as a Service

3. My Journey – How long can it possibly take?
The good
§ DT-wide increased awareness, powerful momentum
§ Connecting the right people within a large organization
§ Researching a diversity of options beyond initial scope
The bad
§ Fear of “cannibalization”, processes, worrywarts
The ugly
§ Opportunism, myopia, politics
My actual CPaaS journey on this year’s launch proposition
started in early 2020.
2020
§ Start with MVP partner, SMS & voice termination
§ Start with informal PoCs, Developer Portal integration
2021
§ Internal awareness campaigns (no slideware!)
§ RfQ CPaaS & Omnichannel solution
§ Vendors, architecture, portal, let’s go
2022

5. Strategic Potential for Telco’s
§ Feature-level analytics
§ API portfolio supporting transition from service to
features + integration and mashup
§ Build base, own evolution, partner for value
creation, develop strategic vertical integrations

CPaaS Iceberg – Theoretical View
Obvious Transition – Proven Enablers
SMS. Telephony. E-Mail. Numbers.
Real-time voice + video. Group communication.

Exposure
New A2P
Channels
Rethink
Telecoms
A2P: Application to Person API: Application Programming Interface

6. CPaaS Enablement
Existing technologies. But better
(mostly A2P: SMS, telephony via
APIs)
Existing business model. But simpler
& more competitive (volume-based,
bundles, per minute)
Existing customer relations. But
simpler, faster, automated (online
management, integrated billing)
Goal: Customer segmentation &
requirement, use case validation.
CPaaS Disruption
New technologies (WebRTC
based voice and video)
Bridging legacy (telephony
breakouts)
New use cases (P2P, group)
API integration (QoS, “Video over
LTE before ViLTE”, “Vo5G today”)
Business model disruption,
(modern enablers, new pricing
models, internal competition)
02
CPaaS Vision
Sustainable communications
layer independent of legacy (e.g.,
IMS + gateway)
Treat communications like any
other online service (integrate
features, measure feature
utilization, iterate fast)
Different carrier relations, evolve
regulations

CPaaS Evolution – Making/Buying/Building APIs does by no means imply we are done!

7. Solving internal challenges…
§ … because eventually the incubation team had to
face the organization and for everyone else it is
business as usual
§ Legal challenges, strategy alignment, ‘failure
mindset’ on paper vs actual, responsibility overlap
§ The idealistic innovation view meets reality
