Replacing a landline phone (sh.itjust.works)

Hi!

I'm looking to replace my family's landline phone with a VoIP based hardphone. From my research it seems that I'd need a SIP server and a SIP Trunk provider. But I also happened to find Jami that has a SIP account feature.

  1. Could I make and recieve calls with Jami over the hardphone similar to a landline phone (minus the ability to call and recieve calls from normal phone numbers) with this setup (SIP server + Jami + hardphone)?
  2. Does anyone have experience setting up a similar system?
  3. Am I overcomplicating things and a used smartphone turned into a softphone would be a better choice?

I've just recently begun my selfhosting journey so I'm not very well versed in networking, but I am willing to put in the time and effort to learn. So any (constructive) feedback/guidance is greatly appreciated!

EDIT: The solution for me it seems is to just buy a used Android smartphone and connect it to a bluetooth handset. Thanks everyone :)

It isn't technically tough to do anymore, but you can only self-hosting the sip endpoint, you need to rely on and pay for upstream trunking.

Also, be aware that 911 or emergency service contact is all over the place. In Canada, VoIP providers do not provide 911 unless they have a pots tie-in somewhere, and there are still tragic issues where 911 calls are routed to dispatchers thousands of km away.

If you have any nontechnical people who expect all the features of a landline using this, don't do it yourself.
