This is a Sonos community, you may get better information on a networking forum. Or by contacting CenturyLink directly.

Thanks. I’ve tried both of those routes but to no avail.

If this is a dead end, I’m open to other suggestions (Raspberry Pi?). I’m fairly competent with technology but a bit intimidated if I need to do any coding that’s beyond cut-and-paste.

There is a frequent poster, @Stanley_4 , who posts about using a raspberry pi solution, since I’ve tagged him, perhaps he can share with you. As I recall, he also has an external website where he has shared his setup process. Let’s see whether he has notifications turned on.
