SIP recommendations - service provider and hardware

[aidan.f]

Firstly, I did search the forum but posts were a few years old, so please forgive me if I'm asking the obvious.

I need to embrace SIP primarially for low cost calls to an octogenearian US residents cellphone.
requirements: CLI is my mobile or home number, good quality audio, actually applies to my end as well!
I have opened an account with Localphone  - then found their andriod app is out of date so tried their PC audio interface - lacks functionality such as audio quality check before dialling my   octogenarian relative. I first called a helpful UK septuganarian and she said the audio quality was poor which could be anything between headphones/PC*/my ISP/Localphone servers
That leaves option of 'some other andriod softphone app' or a proper IP telephone to allow me to spend the £2 credit I have with Localphone. Happy to choose A.N. Other provider.
Looking forward to the usual YACF good advice.

Sounds like you want a US-based provider...

We have localphone which we access using a VoIP/landline phone. We used to use it a lot before we moved to unlimited calls SIMs on our mobiles, it is now used only for the occasional call to America or India.
95% of the time the quality is at least as good as a normal landline.

Thanks Kim and rr.

I'm going to look for a 'proper' phone for my end of the connection
