I used many Internet Telephony Softwares, all of them will work for some days and then stop, but i found that Net2Phone is very good because even if it is stopped by some reasons, within 2 days they will provide new code numbers and it will start working again. But now i stopped using Internet Telephone because i found another very good and easy. That is Invoice from Quest Net, the cost is little high but the voice quality is very good same as line telephone, the company provide us with a trigger number and call back service, just call the trigger number and the company will ring you within 10 seconds and just dial the number you want to call and within 30 second you will be connected without any problem and very very good quality of voice, if anyone would like to register for Invoice service, contact me on my email: email@example.com, i will explane the procedure
Net2Phone allows Internet users to make International phone calls at reduced rates. Indeed calls are free by using the Net2Phone facility built into the current version of the MSN Messenger Service. The downside being that calls can only be made to the US using this software. Net2Phone is a great idea if you are prepared to accept a lower speech quality on your international calls. This is probably only a problem using a modem connection, so anyone with a faster connection probably wouldn't experience any problems. However, because the majority of home users, use 56k modems, the quality may be noticeable especially after using a conventional telephone which now means calls are exceptionally clear. Despite this, some of the costs are impressive and for anywhere other that the US, reduced rates apply and talk time is purchased from Net2Phone directly though their website. I believe that in the long term, services such as Net2Phone will take off, because connection to the Internet will become faster. Nevertheless, in the mean time it is worth trying Net2Phone if you need to make calls to the US because this will not cost anything and for users of the MSN Messenger Service no additional downloads are required.
