Polystar T&M has added new functionality to the PESQ feature in SOLVER.

Now it is possible to measure not only between different interfaces, one can even perform measurement between different types of networks such as GSM and WCDMA.

This gives the great advantage of measuring and finding problems that may occur when calls have to go through several different core network nodes and apply different codecs and speech rates which is normal in most networks.

This new feature in addition to the already existing hand-over functionality (real payload) makes SOLVER an outstanding mobile core network load and function tester.
