I want to buy a voip telephone device, through which I can make cheap international calls. This is possible over various iPhone and Android apps, but since the calls are mostly from the office, I would like to buy a dedicated device for the same.
The device should have a capability to connect to the internet using wifi or an ethernet port ( prefer ethernet port, since the phone will be permanently on the desk )
I found a manual from the provider ( where I have made an account and enabled the SIP server settings ) - https://www.dialnow.com/sip. But, I cant quite understand which kind of device I should buy.
