Hi there.
Are you using Webclients/PWA or mobile applications?

 

[netstreet]

Hi @OlegR_3CX I'm using T23G hadsets

 

[OlegR_3CX]

Do you see that any IP in blacklist?
Are you provisioning them as remote SBC or STUN?
What about actual phone, are you able to access its interface via the local IP and to see if the config file is received?

Hi @OlegR_3CX

The config is received on the phone, There is no IP blacklist on the 3cx. I can access the phone using the local IP swell.
The provisioning method is STUN.

Something strange I pickup is that the reply destination port for the other phones not registering is 1046 and the working one is 5060. Is there any setting I'm missing which only allows for only one phone to be registered to the remote pox?
