A study out of Europe shows that IT executives have a concern about VoIP quality.
I do too. The problem seems to be in my mind a lot of hopping back and forth between networks, both PSTN and VoIP that we experience.
Of late I’ve noticed degrading line quality when calling cell phones, yet, when I make an all IP call, or a pure cell to cell call the calls sound great, indicating that transcoding and mismatched codecs may be the leading culprits.
Hopefully, as more and more companies turn to IP the mobile operators feel the pressure to make more pure VoIP cross connects. That in my view will change the way calls sound and also reduce costs.
