Testing VoLTE devices

3GPP Long Term Evolution networks are now a commercial reality. As cellular network operators continue to plan LTE coverage and capacity expansion, the need to migrate traditional voice calling services to LTE becomes ever
more pressing.

The emergence of GSMA IR.92 – IMS Profile for voice and SMS – as the de facto voice-over-LTE standard has cleared the way for global adoption of a single LTE voice solution. IR.92’s forward-looking foundation on IMS/SIP ensures its longevity, but it also introduces functional, performance, and quality challenges.

Comprehensive testing and verification of VoLTE-enabled mobile devices is crucial to ensuring consumer adoption and commercial success of voice services on LTE.
