Hi I'm getting always "register failed" error on the phone...

But everything is correct, it's still saying:



But on the 3cx side i don't see any attempt.

Have you enable stun on the ext assigned to the base unit, under options



Check the blacklist and delete any entries

Firstly check the phone is on the latest supported firmware then factory reset it.

Follow instructions as per https://www.3cx.com/sip-phones/yealink-dect-w52p/

Run a firewall check on the PBX and make sure it passes.

if it still wont register then you need to either change transport method (TCP/UDP) or look at your firewalls to see why 5060 cant get out/in.

Alternatively, add an SBC to overcome firewall issues.
