Bi-Lateral Vs. Multi-Lateral TDM Minutes ISP VoIP
Bi-Laterals: TDM wholesale voice minutes transactions implies a commercial relationship – typically wholesale termination between 2 parties No such thing as Multi-Lateral in TDM since there is no “peering fabric” and every TDM minute has a $ Value Off-sets: closest thing to “peering” in TDM minutes an agreement where bi-lateral debts negate one another occurs at Layer 2 in the non-analogous OSI model Bi-Lateral Vs. Multi-Lateral: TDM Minutes
ISP Peering: interconnecting at Layer 2 Bi-Lateral Peering: directly between 2 parties who agree to connect typically a “free” exchange of IP traffic occurs on a Public Peering Fabric or via a Private Peering Interconnect (Loop, Cross Connect) Multi-Lateral Peering: Multiple parties all agree to send and receive traffic with each other via a Peering Fabric typically a “free” exchange of IP traffic some instances include “paid peering” costs less than IP transit costs more than “free” Bi-Lateral Vs. Multi-Lateral: ISP
VoIP Peering: The interconnection of two, or more networks Several definitions at Layers 2, 3, 5 and 7 Layer 2 Peering: through a common Ethernet switch most similar to traditional ISP peering distributed peering is possible Layer 3 Peering: VoIP interconnections through the public Internet gateways interconnecting through the cloud usually wholesalers avoiding TDM transport Layer 5 ENUM: can occur through both the Internet and an Ethernet Fabric ENUM – Bi-Lateral and, or Multi-Lateral Layer 7 SIP: can occur through both the Internet and an Ethernet Fabric SIP Peering - Bi-Lateral Bi-Lateral Vs. Multi-Lateral: VoIP
ENUM Registries/Data Stores Currently Available VeriSign E164.org The VPF
Carrier / Enterprise B Carrier / Enterprise A VeriSign: VeriSign Directory Customer Provided L2 or L3 (IP VPN) Link; Handles media streams. Customer Provided L2 or L3 (IP VPN) Link; Handles signaling & routing
Carrier Public Internet Public Internet e164.org: E164.org Directory Users send queries via public IP to e164.org, which replies back with routing info. End User Enterprise Signaling & Media Streams are exchanged between e164.org users directly over public IP.

Who’s Using ENUM Now? Enterprises Universities Carriers (CLECs) Carriers representing End-Users (VoBB) Other Number Mapping Services DUNDi All in an effort to reduce monthly spend on metered telephone calls.
