AnyConnect VPN, some users with Linksys routers unable to resolve DNS once connected.. have to set public DNS servers

Hey all, my company has a VPN group / profile setup specifically for using our VOIP software phones and when some users connect with certain linksys routers it seems like they are losing DNS capability. The only fix seems to be going into their personal home routers and setting up public DNS servers (such as Cloudflare, Google, Quad9, etc). Then at that point I can connect to that Voice VPN profile and we're good to go.

Is there any logical reason why this would be happening? I can't quite suss it out lol.

We're using anyconnect client connecting to a Cisco ASA.
