This document discusses how immmr is bringing traditional voice capabilities together with modern IP-based voice and video communications to create new communication experiences. Key points include: - Immmr virtualizes mobile numbers and allows voice/video communication beyond phones through IP networks. - This enables a hybrid service combining traditional and IP-based calling/video in one service with new business models. - Immmr is working with Magenta to white-label its platform and conducted a UK trial of its "Orbit" product for additional numbers and communication abilities. - Challenges remain in fully replacing telco stacks but benefits of an Internet-based approach can be realized while integrating with legacy networks.

3. We Bring Together Traditional Voice With 21st Century Voice
And Video To Create New Communication Experiences

The boundaries of mobile telephony:
§ Traditional mobile voice and SMS is
limited to the SIM-card and the
phone
What we are doing:
§ Virtualization of the mobile number
and unleashing mobile
communication from its limitations
§ Telco voice and video is becoming a
21st century service beyond telephony
What we are enabling:
§ Combination of traditional and IP based
voice and video within a single service
§ New communication experiences
§ New business models with non-telco
services in the future

9. Challenges Evolving Carrier Voice Communication
…For And With A Carrier

A differentiating experience is key to bridging
Telephony with an Internet service experience.
This will bring both benefits and drawbacks.
Benefits allow user experience that is not possible
or very hard to reach with the legacy Telco stack.
Drawbacks mostly mitigated by integrating with it.
Some key constraints of legacy telephony cannot (yet) be met

10. ”Magenta” Value Proposition
Characteristics as of today
10
Benefits
§ Multi-device, browser capable (“any device”), SIM card
independent (Wi-Fi only)
§ Internet communication over circuit-switched network
(always reachable)
§ Complete postpaid tariff integration – real phone without
any efforts
§ Bi-directional adaptability on changing IP networks
§ Phone-like behavior in apps (e.g. native integration with
CallKit)
Drawbacks
§ Limitations by device operating system towards 100%
dialer replacement
§ Complex communication towards customer since
telephony behavior already engrained
