We generally do not recommend that you use a free VOIP service. There are several reasons why:
1. Skype out, Google Voice, and those type of services use a shared pool of access numbers for outbound calls. Because of this, if you add them to the pinless dial on your account, anyone who is calling from one of these services has the ability to make calls from your account. To prevent this from happening, we actively block known caller IDs from these sites.
Unless you have an upgraded version of the service with your own unique phone number that is passed in the caller ID, you should not enter Skype or Google Voice into your pinless dial settings.
2. The DTMF translation from free VOIP services to our IVR generally does not work. You will find that trying to enter your account number or a destination in India will result in our system telling you that it does not recognize the account number or the number dialed. This is an issue with poor call quality and different signaling standards being used by those systems.
3. Free and low cost VOIP providers often block our access numbers. In cases where they are providing a free service, this is perfectly reasonable, and up to the provider. In the case of cheap VOIP calling outfits, this is often unscrupulous behavior on their end in order to sell you their own international calling services.
If you have a home phone that is VOIP (like phone with your cable system), you will be able to reach our access numbers and make calls, but if you are trying to use a free VOIP service like Google Voice you will may have difficulties using IndiaLD.
