Hey sorry for the dumb questions but new to VOIP... so we currently have fibre with a phone line via My Republic but looking to move away from them to probably Bigpipe or similar.

We only have the phone line for when the MIL stays with us so she has local calling for her friends / they can call her for free.

So, I was thinking of just getting the $10 2Talk home bundle - and then from what I have googled she can get an app for her iPhone that will route the local calls to that?

So, in theory she would open app x - dial the number and 2talk would route it to the normal land line on the other end?

And likewise if someone calls our local 2talk number the app on her iPhone will ring (I assume like Viber or Skype would)

Do I have the technology correct? - and if so can anyone recommend an easy to use VOIP app for 2talk for iOS? Don't mind spending a few dollars on it so long as it's straight forward and works. She will only be using it for calling / receiving calls.

Thanks
