(Top posting to give complete context.) James: Under what conditions will VoIP be used with WiFi access? That isn't the case with my phone (Android, Chattr). At least not automatically. - is Freedom Mobile required? - it is true for my son's (Google US) Project Fi plan - I generally load CSipSimple on my Android devices but I think that the SIP capability is built into modern Androids. - SIP has privacy concerns, even worse than GSM. - who provides the SIP server? I have paid 3rd-party separate ITSP accounts. | From: James Knott via talk <talk@gtalug.org> | | On 04/03/2018 08:33 AM, Tim Tisdall via talk wrote: | > Are you wanting to replace Roger's entirely or just get phone coverage | > in the US?
