I am a vet and on call quite a lot. I live in an area where the mobile signal is unreliable and I don’t have access to a landline. I do however have wifi.
I have been worried on many occasions when the mobile provider’s signal just goes to zero. How will my clients with an emergeny able to reach me. i found a solution in FlyNumber and a separate voip provider I could have used FlyNumber for that too.
Basically I setup a new UK number (as this is where I live). I set the number up so that all calls get forwarded to an ITSP - I already had an account setup with Sip2Sip which FlyNumber recommended. I have a Samsung smartphone where I have installed Zopier and linked it to my Sip2Sip account. However after the recent JellyBean upgrade I seem to have got the phone to take incoming voip calls through Sip2Sip.
I am working at this current practice for 2 months so I went for the three month FlyNumber account but with no repeat subscriptions.
I also setup my phone to redirect all calls when I am unreachable to the FlyNumber I purchased.
So as long as I am logged onto the wifi in my accomodation - or anywhere else and if the mobile signal is lost, then my calls will go via voip to my mobile phone. Brilliant.
