GSM prepaid

Some prepaid uses VOIP, of which the delivery of communications is over over IP networks such as the Internet or other packet-switched networks, or you can call it
Internet telephony. Company that uses this are like Truphone, Jajah, in fact most of the prepaid players in the market, are still susceptible to IP network latency, which can result into low quality voice or lag between caller and receiver as they speaks.

Whereas players like Travelsim uses PSTN (traditional public switched telephone network), of which the quality is unquestionable (so its a challenge for this catergory of player to lower the cost)

anyone knows who else is the true PSTN GSM player in the market, as my company are tired of using VOIP of which our salesperson overseas sometimes has got problem communicating with customers and us in the office and sometime that even happen when we do conference using those VOIP across borders.

that is why we want to subscribe to a very good quality prepaid for our salespeople and also to use it in the office for conferencing, esp when companies like TravelSim has free incoming for so many countries.

I have tried travelsim, its good so far, but the estonian number to call out is not cheap if you are not in europe, though the incoming is good if you are in europe. Therefore we want to have a some proper "Apple to Apple" comparison before we commit to a company wide change to the other GSM PSTN based prepaid providers.

Comments, Folks!
