I just signedup for
www.voipbuster.com. Their rates really looks attractive. Also they have some amazing service. I want to buy some credit from them. Now my questions are
1. They say India to USA, Canada, Denmark and many more countries are free, but I just tried some numbers from my sip phone and got no response.
2. To enjoy free calls do I need to buy credits.
3. Does voipbuster SIP configuration works with GoAutoDial asterisk ?
4. Can I use their service for call center ? Its really unbelievable that I can call to many countries for free form a callcenter.
Please inform me how all these works. Also I see no billing help or direct customer help contact info. So if I need support where should I contact ?
