In June 1999 - Nortel declared a voice over
IP strategy, while Cisco and its newly
acquired Selcius Systems IP PBX were
starting to gain traction. See mobile VoIP blog
and history, and Inca strategy. Nortel was a
leader in enterprise PBXs and made this
announcement to retain the loyalty of their
enormous installed base and to slow down
the adoption of the IP PBX product category.
Nortel overhung the IP PBX market,
announcing products 12 months or more
before their availability.

Open Mobile Terminal Platform - Activities
1
OMTP is perhaps best known for its work in the
field of mobile security, but its work encompassed
the full range of mobile device capabilities. OMTP
published recommendations in 2007 and early
2008 on areas such as Positioning Enablers,
Advanced Device Management, IMS and Mobile
VoIP. Later, the Advanced Trusted Environment:
OMTP TR1 and its supporting document, 'Security
Threats on Embedded Consumer Devices' were
released, with the endorsement of the UK Home
Secretary, Jacqui Smith.

Mobile VoIP
'Mobile VoIP' or simply 'mVoIP' is an
extension of mobility to a VoIP|Voice over IP
network. Two types of communication are
generally supported: cordless/Digital
Enhanced Cordless
Telecommunications|DECT/Personal
Communications Service|PCS protocols for
short range or campus communications
where all base stations are linked into the
same Local area network|LAN, and wider
area communications using 3G/4G protocols.

Mobile VoIP
Mobile VoIP will require a compromise
between economy and mobility. For example,
voice over Wi-Fi offers potentially free service
but is only available within the coverage area
of a single Wi-Fi access point. Cordless
protocols offer excellent voice support and
even support base station handoff, but
require all base stations to communicate on
one LAN as the handoff protocol is generally
not supported by carriers or most devices.

Mobile VoIP

As device manufacturers exploited more
powerful processors and less costly
memory, smartphones became capable of
sending and receiving email, browsing the
web (albeit at low rates) and allowing a
user to watch TV. Mobile VoIP users were
predicted to exceed 100 million by 2012
and InStat projects 288 million subscribers
by 2013.

The mobile operator industry business model
conflicts with the expectations of Internet
users that access is free and fast without
extra charges for visiting specific sites,
however far away they may be hosted.
Because of this, most innovations in mobile
VoIP will likely come from campus and
corporate networks, open source projects like
Asterisk (PBX)|Asterisk, and applications
where the benefits are high enough to justify
expensive experiments (medical, military,
etc.).

Mobile VoIP - Technologies
Mobile VoIP, like all VoIP, relies on
Session Initiation Protocol|SIP — the
standard used by most VoIP services,
and now being implemented on
mobile handsets and smartphones
and an increasing number of cordless
phones.

In this case the use of 'mobile VoIP'
enables a continuous conversation that
originates, and ends with, a wired terminal
device.

A more popular approach has been fullspectrum handsets that can communicate
with any wireless network including mobile

but which have limited handoff capabilities

Mobile VoIP - 2011
As of late 2011, most cellular data
networks were still extremely high latency
and effectively useless for VoIP. IP-only
providers such as Voipstream had begun
to serve urban areas, and alternative
approaches such as OpenBTS (open
source GSM) were competing with mobile
VoIP.

Flat rate - Telephony
1
American Telecommunications companies
commonly offer a flat rate to residential
customers for local telephone calls.
However, a regular rate or Message Rate
is advantageous for those who only make
a few short calls per month. Flat rates
were rare outside the USA and Canada
until about 2005, but have since become
widespread in Europe for both local and
long distance calls and are now also
available for mobile phone services, both
for traditional GSM/UMTS voice calls and
for Mobile VoIP.

Truphone - History
Truphone was originally formed to
develop downloadable mobile VoIP
application software|applications for
smartphones, using the integrated WiFi|Wi-Fi connection on the device.
These offered the ability to make free or
low cost calls on the mobile device in
areas where there is weak or no GSM
coverage, and to send Instant
Messages to other networks.
