5. What is SIP trunking?
Direct IP peering between SIP- Based on reference architecture
enabled IP PBXs and Service defined by SIPConnect Forum
Provider SIP-enabled networks Replacement of TDM-based
Converts TDM trunks on-site to trunking (PRI and CAS trunks)
SIP-based media streams to the Logical SIP trunk overlaying
carrier network IP network
Based on mature SIP standards

7. Challenges facing SIP trunking
Adoption
– Under 3% of current trunk installations,
but growth is rapid (300%+/year)
Availability
– Limited pool of providers, but expanding rapidly
Standards
– Service Providers’ offers diverge greatly
Interoperability
– Legacy TDM platform must be converted to SIP
through voice enabled router
SIP signaling implementations can hamper
performance/security
– Some vendors only implement specific
SIP signaling mechanisms
Security
– IP communications and UC networks require
security, just like data network

8. Benefits of SIP trunking
Lower telecom costs by 30-70%
Improve stability by moving all
technology into centralized data centers
Business continuity/disaster recovery
Answer all calls all the time no matter
which number a customer calls on (local
or toll free)
Improve productivity by further
integrating communication with people,
process, and information
100% call recording for industry
compliance, quality monitoring, and
speech analytics
Foundation for UC deployments
(audio/video conferencing, presence,
chat)

10. Industry observations
―SIP trunking services have been commercially available since 2005, but
only now are enterprises grasping the business case, which can be very
compelling within certain enterprise segments‖
Brian Partridge, Yankee Group analyst
―SIP trunking revenues will be about twice as large a revenue stream as
hosted PBX services by 2012, possibly representing about $10 billion
worth of annual revenue.‖
Frost & Sullivan
―There are some technical hurdles to overcome when deploying SIP trunks,
but most of them were related to the fact that most firewalls and other
traditional security cannot handle the bidirectional nature of voice and
other communications— most of which can be overcome through the
use of a session border controller.‖

TDM-to-IP transition well underway
– Reduce costs, improve communications efficiency
– Mobility, collaboration, presence and
video drive IP transition and complexity
– Compliance – call recording, emergency services,
domain separation
– IP PBX extensively deployed but exist as islands
Unified Communications (UC) is the new focus
– Migrate mission critical applications onto IP network
– Integrate chat, voice and video into contact center
and business applications
– Introduce presence and mobility into application delivery process
– Transition call centers to multimedia customer care centers
SIP trunking can reduce voice trunking cost for an organization by
50% of more
– Most implementations have a positive ROI in less than one year
SIP Trunking is not an all or nothing endeavor
– Start with moving outbound voice traffic to SIP trunks to get a quick
ROI with little risk and keep the existing PSTN trunks as a backup
