SIP End Points

Ixia (News - Alert), a global provider of converged IP and wireless network test solutions, has introduced a new VoLTE application, with SIP end points capabilities, that is designed to put HD voice to the ultimate test.

The company will demonstrate the new industry-leading VoLTE test solution at Mobile World Congress (News - Alert) 2012 from Feb. 27 to March 1, in Barcelona, Spain.

Officials with Ixia said that the company has introduced new test application to its IxLoad solution to measure voice quality end-to-end, from the cell tower through the core network.

Thanks to this, operators can easily compare and contrast the voice quality of over-the-top (OTT) service to operator-provided voice services. Using best-in-class industry algorithms, operators can measure the mean opinion score (MOS) of voice quality before going live.

Company officials said that besides this, Ixia's new application tests the functionality, scalability, and resiliency of LTE infrastructure components and new IMS networks that support VoLTE-based services. The application’s VoLTE features also include support of the GSMA (News - Alert) IR.92 specification and emulation of SIP end points to initiate and receive voice calls and SMS texts over eGTP.

According to company officials, Ixia's IxLoad is a unified test solution for testing all aspects of wireless networks end-to-end, including LTE base stations, core network components, and the IMS subsystem.

IxLoad supports a broad set of test applications measuring the scalability and capacity of data applications, the quality of rich media services, and the evaluation of security vulnerabilities.

"The demand for high-definition voice and other media-rich features is growing with the number of mobile users and devices accessing the Internet. Operators must be sure that their new LTE networks can deliver high quality voice services," said Joe Zeto, senior manger of market development at Ixia, in a statement.

Zeto said that Ixia's new VoLTE test application allows operators to validate their networks under realistic conditions.

"Mobile VoIP subscribers (Over the Top) growth is predicted to be 386M in 2015, led by Skype (News - Alert) and GTalk Mobile, but generating little revenue. Now operators must compete to preserve their $500 billion per year in global business under attack," said Stephane Teral (News - Alert), principal analyst at Infonetics Research.

Teral said that VoLTE allows operators to offer a differentiated solution. This important demonstration shows that Ixia can test VoLTE implementations so operators can go to market with confidence.
