PSTN to voxalot to justvoip or poivy or any other betamax service possible?

[ramsudhir143]

I am very much new to this VOIP/SIP world. I have an account in justvoip.com, It really costs very less to place international calls. However I dont have access to internet always to call from justvoip.com. I am just thinking if I can use my mobile to call VOXALOT(through SIPbroker PSTN access number) and VOXALOT reroutes the call to my justvoip.com account?

I am very eager to know if this is possible? so that I can place my calls directly from my mobile insteading of logging into justvoip client on internet. Calling from mobile is more flexible because you can call wherever you are.

Please let me know if you have any other alternative. please let me know if this is possible or am I being just too ambitious.

If justvoip.com is not possible, is it possible to use poivy.com or any other betamax service.

Thanks in advance.
