IP Telephony news wrap-up for Jul 26 – 2006

Brix Networks has reported that test results generated by a web-based application to test VoIP call quality from a consumer’s PC to select global destinations shows that there has been a consistent decrease in overall voice quality, based on the use of this application over the last 18 months. The company claims that 19% of calls initiated through its testing mechanism achieve less a MOS score of 3.6.

Brix tests calls using an applet that initiates a test phone call using SIP. Appliances answer these calls and measure QoE. The appliances, products sold by Brix under the brand name Verifiers, are currently installed for this web based testing service in Boston, Helsinki, London, Montreal, San Jose, Sydney and Vienna.

In addition to being able to access the service for free at www.testyourvoip.com, Brix has partnered with Google to have the application offered as an optional feature of the portal giant’s desktop. When embedded as a Google gadget, the application displays a weather map indicating the Internet’s current ability to support VoIP and IPTV.

Variables that weren’t addressed in Brix’s report include the impact of increased usage of its service and the impact of adding more Verifiers to the service. When the service was initially launched, call quality was only measured to two locations. Obviously, if I am in the U.S., I can expect more consistent call quality tests to Boston and San Jose than Helsinki and Sydney.

Kaynam Hedayat, VP of engineering & CTO at Brix agreed that these variables existed and that the data recorded pertained exclusively to voice traffic over the Internet, leaving the issue unclear as to how QoE might exist on private networks or networks dedicated to VoIP.

Brix’s tool is a great resource for consumers, but unless the influence of all of the variables are defined including concession that the application doesn’t indicate how each individual network will carry a call, it could be misleading.

GlobeCall has built a nationwide VoIP network in Brazil. The network is driven by Quintum’s Carrier MultiPath Switch, deployed at the carrier’s headquarters in Rio de Janeiro and by the vendor’s Tenor CMS 240 units, which have been deployed at PoPs within the network. For CPE, GlobeCall is using Quintum’s Tenor DX, AX and other Tenor family products.

PL Technologia served as the systems integrator.

Quintum Technologies has introduced Tenor VoIP Call Routing Server II, a new routing server that allows calls to be routed based on a variety of parameters including QoS-based routing that automatically routes calls around any portions of the network that are not supporting acceptable QoS characteristics, least-cost routing, source-based routing, route quality, best pattern match, circuit routing, domain priority, and load balancing. The server also controls access to the voice network by disallowing endpoints, providing control over unauthorized access to your network resources.

The server offers centralized network routing management, allowing for multiple units to be deployed within a voice network, without the need to modify individual gateways. Each can support up to 72K BHCA. Management is accessed through a web GUI.

Other features include the generation of network call routing statistics reports based upon either historical data or real-time activity. E-mail alerts are provided to inform the network administrator of network failures or suboptimal operating conditions.

The Tenor VoIP CRS II is available for $8,000.
