Welcome to Voipuser forums.
The trouble with "free voip" is that it costs money to provide voip and cost even more if PSTN come into the picture. If both ends of the of the potential call have good high speed internet then you can use SIP (eg. Voipuser accounts) or Skype to make calls between computers. Calls to regular phone from computer to Singapore cost only about 1 cent (or less) per minute. It is also possible to use iNUM to make calls.
If you plan to make a lot of calls is is probably better to use ATAs at both ends to get good quality sound and the calls will be "free". |
