Having the Voom 3 5x static IP service installed in a few weeks and understand that their kit will need to be "modem-only" mode to support this
If this is the business service it may come with a Hitron modem, whereas the consumer service comes with the Hub 3 (or Hub 4 for Gig1).
No idea on how the Hitron works, if it is just a DOCSIS modem that you connect your own router etc to. If this, then you might need a higher grade of router than your usual domestic to use 5 static IPs. (e.g. a Draytek or Ubiquity etc).
The Hub 3 is easy to put into modem mode and use with your own router, but this service is only 1 public IP which is dynamic (but very sticky).
Depends which mesh system, some are not suitable for connecting directly to a public IP and only handle WiFi, others do the full routing. (e.g. Google Nest WiFi).
