So my mother-in-law recently moved in with me, and we currently have a Cox landline. She has her own CenturyLink number, and I was told by a Cox technician that I could simply plug her phone into my landline and she would still be able to use her number. However, that didn't work at all. Was the technician misinformed? She really needs to keep her CenturyLink number since she's 86.

It sounds like the Cox tech was oversimplifying things. You can't just plug a CenturyLink phone into a Cox line and expect it to work. Phone numbers are tied to specific providers, not the hardware. If your mother-in-law needs to keep her CenturyLink number, you'll have to request a number port from CenturyLink to Cox. Just a heads up, it usually takes a few days to process, but that's the only way to keep her number.
Definitely reach out to CenturyLink directly for the best guidance on this. You might also want to consider using a third-party VoIP service like Ooma. By porting her number to a VoIP service, she could still keep her number while being independent of the actual internet provider you use.
