VeriSign Communications Services Interoperable with NetNumber

By Anuradha Shukla, TMCnet Contributor

VeriSign Communications Services and NetNumber have announced the successful certification of the VeriSign (News - Alert) NRD4.2 software release against the NetNumber software version TITAN 6.7 that implements the PacketCable ENUM Server Provisioning Protocol (ESPP).
The VeriSign Network Routing Directory is a carrier ENUM registry utilized by the global telecommunication industry to simplify the administrative complexity of internetworking. The directory facilitates the rapid exchange of routing information between network operators.
The NetNumber (News - Alert) TITAN platform can be used by the network operators to host inter-network switch translations downloaded from Carrier ENUM registries, such as the VeriSign Network Routing Directory.
According to companies’ officials, interoperability between the VeriSign Network Routing Directory and the NetNumber TITAN platform can deliver end-to-end Carrier ENUM services to network operators that adopt the PacketCable specification.
A multi-operator interconnect registry provides a solution to out-of-synch databases and disparate switch translations. This increases the efficiency of intercarrier connections and results in call completion directed towards least-cost interconnects.
Paul Florack, vice president of Network Services, VeriSign noted that one of the major reasons their customers use their service is its support of an open multi-vendor environment.
“Service providers can request the registry using the standard PacketCable ENUM Server Provisioning Protocol (ESPP) to replicate to third party platforms within their span-of-control.”
According to Florack, exchanging and synchronizing the most cost-effective routes, programmed automatically, can avoid the problems and associated costs of mistake-prone manual labor.
Glenn Marschel, NetNumber CEO explained that the TITAN server provides Network Routing Directory, NRD, with a mechanism for allowing carriers/operators to download and access a local copy of NRD data for use in the local addressing and routing process.
“Application specific addressing and routing services supported on TITAN using NRD data include but are not limited to: number-portability services, ENUM routing services, SIP-redirect services, SCCP/GTT flexible numbering services, etc.,” added Marschel.
