I am looking to building my own phone from a SBC running a linux distro with plasma mobile and that can make calls. and I have some questions:
Where can I start?
Which SBC to choose?
How would I achieve the call functionality?

To add, in the US, most service providers will not let a device on their network until it has gone through FCC approval. You can get around this by buying a cell module, which has gone through approval, but most of those are data only last I looked.
