Intelligent Interconnects in the
VoIP Peering Environment

Defining Voice Peering
• VoIP Peering can generally defined as a process
of interconnecting two different VoIP networks
with or without an underlying commercial
relationship associated with the voice traffic
• Intelligent VoIP Peering can be realized when
business logic and intelligence are applied in the
address resolution process to enhance the
interconnect (quality), value or reduce cost (LCR)

VoIP Islands: With ENUM
• ENUM capability enables signaling (address resolution) and direct
interconnects between VOIP networks
– After ENUM lookup, the PSTN is by-passed with efficient and cost effective
use of VoIP networks

Cost Reduction using ENUM
(Example: North America Termination)
• Cost reduction can be significant savings as ENUM
registries and databases expand
• Example: A carrier terminates 4 Million minutes/day to
North America region
– If 1 % of termination points are reached via
ENUM and NA termination cost is $0.005 per
minute (Average)
– Savings per day: $200.00
– Savings per year: $73,000.00
• At 10% address resolution via ENUM , yearly savings
increases to $730K!

ENUM/Peering Benefits
Advantages
• Capitalizing on the “Trend is our Friend” Model (TDM to IP
migrations) within the carrier industry
• Reduction in circuit MRC
• Reduction in CapEx (GW and DACS ports, A/C, colo
space, maintenance costs, etc.)
• More use of SBCs (SBC ports are less expensive)
• ENUM Address resolution is simple (DNS-like) and can
scale highly
• Use of ENUM services to enable direct IP end point
termination (at significantly lower costs)

ENUM/Peering Concerns
Issues and Concerns
• Lack of CDRs since many of these peering networks are transport
• Troubleshooting – may (often) require all three parties involved to solve
issue
• Peering network business models may not make sense although these
models are in process of definition (flat rate, Volume-based,
membership, or per query models)
• SPIT and VoIP security concerns when ENUM registries are “open” to
queries
• Hidden costs: Peering fabric/networks still need to address issues
associated with IP physical transport (Private vs Public networks),
Discovery/Location, interworking, interoperability, media and transcoding, policy/trust/security, commercial, etc.

A TDM or VoIP call enters iBasis
Network
The E.164 (phone) number is
presented and resolved through an
ENUM registry or DB (Intelligent
Business Logic is applied)
A SIP URL and IP End-point
identified with the E.164 phone

VoIP call is terminated at lower cost
directly to the IP Phone or PC client

Uses of ENUM and Intelligent Peering
• Intelligence and business logic can be applied to the ENUM data, not
just E.164 to SIP URL
– Carrier-ENUM: Direct Peering and toll by-pass, private, secure, operatorcontrolled discovery of IP-based applications and services.
• SoIP: Service over IP controlled end-to-end SoIP addressing includes
VoIP and Video over IP.
– Routing with or without business logic applied: LCR, Quality, Route
Optimized
– Number-Portability (LNM/MNP) : Highly efficient portability resolution with
traditional SS7 interfaces.
– Calling Party Identification (CPI): Highly flexible, carrier-defined CNAM
address resolution logic including integrated access to the industry leading
TARGUSinfo CNAM database.
– SMS and MMS: Portability-corrected addressing for cross-operator
(mobile operators) SMS and MMS services.
– Special routing applications (TDM-VoIP Call Diversion with Presence
Databases)
– Redirecting undesired traffic - Fax and Modem Re-direct

Summary
• ENUM is a technology that can provide for
intelligent interconnects across multiple IP-based
services and applications
• With the use of ENUM, intelligence and business
logic can be applied to each specific service to
enhance its value.
• Business models may change and need clarity.
• The future use of intelligent peering and ENUM will
provide for new exciting services in the near future.

Key Discussion Points
•
•
•
•
•
Will peering work and how will service providers make money?
Will carriers provide the numbers needed for ENUM registries?
Will the hidden costs hamper the growth or peering and use of ENUM?
Will MNP/LNP be the first practical use of ENUM?
How much will we invest in securing the data? Is this a major concern
amongst end-users and carriers?
• Should wholesale carriers consider the creation of their own peering
and ENUM registry solution for routing and number portability?
– Who are the major technology enablers (registries) of ENUM?
– What are your organization’s thoughts on ENUM?
