Solved T46S duplicate on phone list

[ikon1]

I have 3cx setup on the cloud and a T46S that provisioned with STUN. For some reason this phone shows up with 2 duplicate MAC on the phone list. Provisioning the phone is normal, the login screen comes up and provisions. However, after it comes up there is no service. Other phones which are the same model work fine. I've tried reprovisioning and the same problem occurs. Firmware is up to date and is the same as the other functional phones. There are no other extensions that use this MAC. The duplicate phone shows up as the same extension. Any suggestions?

Hi,

A very similar discussion took place here recently, you might want to take a look: https://www.3cx.com/community/threads/duplicate-grandstream-phones-showing.87493

The short version is:

a) It's preferable to use an SBC as it will solve many of these issues (and some other future ones). We highly recommend this!

b) If you will use STUN make sure that all the points here have been met 100%

I ended up fixing it by port forwarding on the firewall. I thought about SBC but it just was not worth the trip.
