Credit on pc phone

[Lorence]

Hi guys.......I have a phone program called IPHOX installed on my pc that allows me to make free land line calls from my pc....All other calls ie. Mobiles,International can be made if I have credits in my account. I've heard that there's a way of adding credits for free.....Does anyone know how it's done or is it just Bull....Thanks for any info
