I use a SIP provider for the landline at home. When on vacation I want to be able to make outbound calls with my landline number. I know this can be done, but I have no idea how. Does anyone here have some pointers for required hardware, software and configuration?
Just use a sip phone app on your mobile. I use Linphone but there are lots of them.

For anyone that needs a guide. Should work for most providers with some configuration changes.
I do this with avm fritz box, it can take the physical line and act as a sip server on the lan. I connect via the integrated wireguard VPN and use portsip app for make phone calls
I use this.
I have Ms VoIP as my provider. $1 month per line and 1 cent per min.
I have a grand stream sip adapter… Configured with my providers info and my creds. Phone can plug into it. Works just fine. Plus you can use any sip client to connect to the same line from mobile or PC.
Also, my old house had pots lines in every room. I took my grand stream and wired it into the house, not a phone. So I can plug regular phones into any of the original outlets and it works as it directly connected to the grand stream. I have 4 regular phones all running over original wires into the grandstream using sip

You might need to set a STUN server or similar, in settings.
Check with your provider for SIP server, username and password, and if they have a suggested app (even if you don’t want to use it, it means they have some kind of support). It’s probably in their support pages somewhere.
You can install Linphone from the Fdroid repository, and register it with your SIP provider as an extension. How you set it up as an extension will vary by the provider.
