–Mobile infrastructure includes the systems and tools that
are used to secure corporate assets, remotely manage
devices, and enable applications for workers who spend
significant time away from the office.

sip trunking
‣ session initiation protocol: standard defined by RFCs
‣ an IP-based “handshake” to set up, destroy, or modify a
communications session between two systems
– trunking: to the PSTN (public switched telephone network)
‣ connects using any IP network, including internet

5 reasons sip trunking is “it”
‣ many major iLEC and cLEC provide enterprise
on-net SIP trunking options in the US
‣ many ITSPs (Internet Telephony Service Providers)
use SIP trunking as well

5 reasons sip trunking is “it”
‣ large investments and commitments by
leading VoIP/UC vendors

5 reasons sip trunking is “it”
‣ open standard promotes adoption and expansion
– built to be network-based communication standard
– 200+ extensions for enhanced security,
features/capabilities, interoperability, wireless
(3GPP), IMS
– not controlled by single corporation

5 reasons sip trunking is “it”
‣ designed to facilitate more than just voice
– embeds sdp (session description protocol) to
allow setup of various supported media types
‣ supports messaging and presence (availability)

5 reasons sip trunking is “it”
‣ savings from sip trunking can help business
case for uc
– trunking consolidation reduces unused capacity
– higher density of concurrent calls per circuit
– lowered cost per minute to PSTN

uc solutions: not so unified
‣ “silos” of uc technologies
– proprietary systems deliver seamless end-user experience
– different backgrounds, visions, focuses, delivery methods

uc solutions: not so unified
‣ all vendors have different strengths/weaknesses
– no single vendor makes the silver bullet
– perpetuated by continuous development of tech

top 5 considerations for a
uc infrastructure with sip trunking

top 5 uc considerations
‣ make sure your LAN and WAN is voip/uc ready
– understand the infrastructure requirements that
are necessary to support uc
– LAN: architecture, duplex, capacity
– WAN: QoS, adequate bandwidth for growth, low
latency, jitter, packet loss
• Make sure it actually works (e.g. tested!)
– network is number one culprit for poor uc
performance and adoption

top 5 uc considerations
‣ use sip trunking unless you
have a good reason not to
– enough interoperable service
providers now
– foundation for next decade of
communications
– be careful about ITSPs due to
Internet links

the mobile infrastructure experts 20
top 5 uc considerations
‣ understand how your business
departments and users
communicate and collaborate
– be methodical and as objective as
possible
– use surveys, evaluate IT/IS
systems, user categorization
– take quantitative measurements of
task efficiencies (create a baseline)
– determine “hot spots” where
improved communication can make
a measurable difference
© 2010 Unwired Revolution. All rights reserved.
the mobile infrastructure experts 21
top 5 uc considerations
‣ evaluate multiple uc vendors
– attend seminars, watch demos, read white papers
– rate strong and weak points of each
– determine how well each delivers on your “hot spots”
– generally the larger the organization, the more
vendors required to build solution

the mobile infrastructure experts 22
top 5 uc considerations
‣ phase-in the deployment of
your uc systems
– consider implementation
specialists
– highest value at least cost
pieces first
– pilot and test each phase as
much as possible
– provide end-user training
– test test test before rollout
– don’t forget security

‣ mobile voip (FMC)
– SIP, VoWiFi, eventually Vo3G/Vo4G
– use of smartphones as primary office extension
– field testing a couple of different solutions
‣ communications enabled business processes
– context-aware IM, voice, contact list (presence)
– field workers have quick access to knowledge
workers via multiple communication methods

wrap up
‣ sip trunks are crucial for today’s and
tomorrow’s uc infrastructure
‣ sip trunking can tremendously help
the business case for uc deployment
‣ an inGate SBC is critical to help with
sip interoperability, enablement and
security
‣ “full uc” is non-trivial, usually involves
multiple vendors and phases
‣ an integration partner is very valuable
