Hi,
I am a residential customer and have Starlink internet service.
I want to replace my landline with the most simple and cheap internet based phone.
Can you tell me what I need to buy, and if a subscription or anything similar is needed.
In order to use an IP phone you need internet, an IP phone and a phone service provider. If you already have internet the next step will be to find a suitable voice provider and then you can check with them which brand of phones they prefer to work with and lastly you order the phone.
