General VoIP DiscussionThis forum is for issues that do not relate to either a specific provider or a specific vendors hardware. General issues that affect the advancement of VoIP as a whole.
I have DSL service in US and in India. I have two Sipura 2100 devices. Anybody please tell me how to setup VoIP -device to device without service provider. Anyway I don't connect through PSTN lines so I would like to have my own phone number for each device (some random numbers) so that I can call 100% free. First of all is it possible to setup like this without service VoIP service provider?
