Hi there I am currently using a Cisco Small Business Router SRP527W.

I'm currently on ADSL but want to swap across to VDSL

I would also like to change providers (to Voyager Internet). They provide a managed router Zyxel VMG8324 for $10/month.

I am wondering whether my current Cisco SRP527W can be used with VDSL.
Or should I swap across to the Zyxel?

I'm using 2 VOIP phones in the office, and 4 PCs hooked up plus other devices on wifi.
