4. Progress ?

5. The
Evolution
of
Enterprise
VoIP
• First
:
Replace
the
RJ-­‐11
– Immediate
gains
in
CAPEX
as
single
wiring
harness
simplifies
campus
management.
– Greenfield
ROI
–
NO
Brainer
• Second
:
Replace
the
TIE
Lines
– Integrate
Enterprise
wide
Dial
Plan
Management
into
single
IP
Network.
Immediate
OPEX
gains.
• Third
:
Replace
the
PRI
(Today)
SIP
Trunking
– All
IP
E2E
• Fourth
:
Direct
Peering
with
Business
Partners
– The
40-­‐40-­‐20
rule
• Fifth
:
Seamless
Campus/Mobility
Integration
– Its
not
fixed
Mobile
Convergence
its
Substitution

• Increasing
progress.
• Market
awareness
increasing
monthly
..
• Better
Faster
Cheaper
• ROI
is
clearly
demonstrable
• 40%
savings
increasingly
reported
• SIPforum’s
SIPconnect
1.0
and
soon
1.1
• http://www.sipforum.org/sipconnect
• Carrier
support
increasing
among
Incumbents,
CLEC’s
and
particularly
MSO’s
(Good
numbers)
• So
Long
as
PSTN
(PRI’s)
is
used
as
the
inter-­‐VOIP
“default”
network
service
will
be
degraded
as
it
must
transverse
multiple
networks

7. Why
SIPconnect?
SIP
is
nearly
150
individual
“Request
for
Comments”
standards
from
the
IETF
– Nearly
100
more
are
in
the
pipeline
• Industry
needed
a
standard
implementable
“profile
of
SIP”
• Users
needed
brand
awareness
of
SIP
Trunking
features
and
benefits
• Maintain
“Voice
Centric”
focus
• Strengthen
MUST
vs
SHOULD
‘requirements
to
implement’
for
both
PBX
and
Service
providers
• Create
forum
for
interoperability
compliance

SIP
Trunking
• Class 5 is dying ( its about time) though the FCC
hasn’t been told yet. Title 4?
• Collapse of Nortel has put Carriers on notice
• So what are you going to do with those DMS 250 / 500’s
– End of Life letters for 5ESS?
• SIP
networks
are
still
being
“Dumbed
Down”
at
the
point
of
carrier
interconnection
• Considerable progress however.

9. Service

Service
Provider
SIP
Trunking
• GSM Operators (IPX/Pathfinder) – International
Interconnects (i3Forum) and the North American Cable
Operators (CableLabs) are in general technical
agreement.
• Conversion held up due to substantial capital constraints.
– The economics in Telecoland not healthy even in
mobility.
• CAPEX trap. Mobile Data Backhaul dominates.
• TN routing data Carrier ENUM initiatives are the looming
issues
– SIPD base routing still dominates ( Who is the Carrier of Record?)

10. FAX
• Ongoing issue
• Contrary to popular opinion FAX is still a
essential communications service and is actually
increasing in popularity due to regulatory
requirements ( HIPAA – SOX )
• Sort of works with G.711 – G.729 (no way) or
with any HD voice codec.
• SIPforum Fax task group coordinating with
i3Forum.

11. E.164
resolution
• This
is
not
a
ENUM
lecture
..

• Advanced service delivery based on E.164
numbering will not occur without killing off
TCAP/SS7 eventually.
• Good
news
its
in
the
field,
well
supported
and
it
works.
MMS
success
story
• The future of SIP and the teleco industry is
tied to making the Voice Service relevant. HD
voice needs a new signaling model.

12. OSS/BSS
problems
• Architecture is sexy billing systems are not.
• Carriers are Spending Millions to accommodate SIP
Trunking and in the process canalizing existing revenue.
• Number Routing Databases not standardized
– Provisioning IP data in intra vs inter carrier routing tables.
• In general operational issues related to OSS/BSS are
being lost in the shuffle.
• CONCLUSION : We still have a long way to go.

13. The
real
industry
problem
is
Layer
8
(financial)
ARPU
• Money is the answer what is the question ?
