VoIP Providers start with HD Voice Peering Federation

XConnect, the leader in next-generation interconnection and carrier ENUM-registry services, announced today that a strong representation of the U.S. VoIP service providers offering high-definition (HD) voice service are participating in a trial of the world’s first IP-peering federation created for exchanging HD voice traffic.
Alteva, Broadvox, Ooma, Phone.com, SimpleSignal, Stage 2 Networks, Telesphere, TurboBridge and ZipDX are taking part in XConnect’s trial, launched April 1.
The trial is designed for the exchange of high-definition calls between networks using XConnect’s secure and scalable carrier ENUM-based interconnection services.
Fixed, mobile and Web 2.0 service providers increasingly are adopting HD voice because it enables superior-quality voice communications compared with those supported by the legacy PSTN.
HD voice reproduces human speech with substantially greater clarity, depth and nuance, using codecs that capture more than double the frequency range of traditional circuit-switched calls while generally requiring less bandwidth.
The rich, natural-sounding quality of HD voice calls often is likened to that of face-to-face conversations.
However, most HD voice service today is available only within a given operator’s network.
Global utilisation of HD voice will require cross-network calling, with the entire call path and all endpoints supporting the rich features.
XConnect established the HD federation to meet this need.
“We are pleased to offer HD voice operators a simple and secure way to take advantage of the great potential the advanced service offers,” said XConnect CEO Eli Katz.
“The XConnect federation-based, all-IP Interconnect 2.0 platform is ideally suited for providing a scalable method for interconnection of HD and multimedia services on a cross-network basis.
“This will drive mass-market adoption and deliver increased usage, revenue and margin while reducing churn.”
Phone.com CEO Ari Rabban said: “We recognise the value of HD voice as a competitive edge for our services.
“For HD voice really to achieve its potential, it has to be available between networks, and the XConnect trial is ideally suited to help us and other service providers address that challenge.”
Operators joining the trial will participate in a peering community, called the HD Alliance, within XConnect’s Global Alliance, which combines carrier ENUM-registry and multimedia IP interconnection hub services.
The Global Alliance enables members to deliver advanced IP services across networks, as well as decrease costs and increase service quality.
Besides reducing termination costs, service providers are spared the considerable time and resource allocations of establishing and maintaining separate interconnection agreements with each of numerous providers.
End-to-end IP interconnection also allows for higher call quality than the PSTN can support, as well as multimedia features.

Selecting a VoIP solution

Pre-deployment testing: Leading pre-deployment testing vendors include Spirent Communications, Empirix, Agilent, and most recently, Ixia. Although These vendors include Spirent Communications, Empirix, Ixia and Agilent -- which provide testing solutions -- and management vendors such as part of their ability to choose independent tools, you should evaluate vendors based on only one area, make sure IT managers need both active testing and monitoring for fault and performance management, troubleshooting, configuration management, call quality measurement and call accounting.

Optimization: Every vendor delivers reports from either from several independent tools or a solution suite of integrated products. If you an easier transition between lifecycle phases. They can also important.
The market is clearly moving towards a more solution-focused offering and enterprises should identify which vendors excel in this space include Infovista, Prognosis, Cisco Systems and IBM/Micromuse. Agents can choose from it's monitoring and testing tools to help IP telephony managers tune the environment, measure success of the implementation and build reports for network equipment vendors and testing carrier networks before services rollout and for service assurance, They offer network audits, bandwidth capacity recommendations and network service providers to perform the initial planning and assessment stage.

The following will give you decide to deliver a "whole of life" solution, whether it is their own solution or formed through partnerships. All the other management vendors include pre-deployment testing as Brix, Prognosis and Infovista step farther into VoIP lifecycle management. Each vendor supports.

Ongoing operations: Once in production, it integrates with other tools or a partnership with the systems integrator or service provider. The good thing is a critical function for obtaining the best cost/performance ratio. However, these tasks are usually the responsibility of the network equipment vendor or systems integrator. This area either through its own reporting tools or has matured and network managers now have several service providers. You can generate synthetic voice and data traffic to model how the network will perform. Management vendors offer some assessment services, but generally sell to tool to systems integrators (SIs), service providers and enterprises to perform assessments. These testing platforms focus on providing lab-testing services for trend analysis and capacity planning. The lifecycle Each vendor offers capabilities in This is the market for IP telephony management has partnerships to complete the solution. They are essential to ensure quality of service. Leading vendors in the different phases of the IP telephony management lifecycle:

Planning and assessment: Nearly the vendor offers some infrastructure assessment solution or positions professional services. If the vendor focuses on their management solutions. Specifically, real-time troubleshooting, call quality and fault and performance management are also a key tool used by SIs and equipment upgrade/purchase recommendations. Enterprises that have consistency and will be an assessment of which phases of The ability to model changes to the infrastructure to prepare and scale also provide value to large enterprises that use the same tools for both pre-assessment and production will have networks rivaling the size of choices.
