Need a little help here.

Unifi ONR has VOIP.

Upgraded to Asus AX-6000 router because Unifi ONR cannot handle too much wifi clients.

Changed ONR setting from router to bridge.

But this causes VOIP not working because it is not routing VOIP anymore.

Should i call TM to solve this or i can do it myself in UNIF ONR or AX-6000?

I could just change Unifi ONR back to router and make the AX6000 as AP.

But it seems like wastage of performance from the router.

Guidance needed.
