Hello @Maykel Constantin

Please provide some information regarding your installation. What version is the PBX? Also is it a cloud or a local installation? Is the phone local to the PBX or remote?

Local install, 0 firewall i did like 500 time whatever is on that link pbx version 15.5 and its remote ext.. its look like the phone never send the request to the pbx the only way i get connected is by adding the sip account manually on the phone.
 
First thing to do is check that you pass the firewall checker. Once you do make sure that the phone is on the supported firmware and to provision it again. Make sure that under the extension settings / Options the option "Disallow use of extension outside the LAN" is nor enabled.

Thank, i did that i download the support firmware all my ports are open i dissable that options under options on each extentions and still cant get the phone to provision to the pbx. :(
 
How did you setup the phone under the extension settings? Did you select the provisioning method to be STUN? If so press OK on the extension and navigate back to Dashboard. Do you see the RPS request successfully sent?
If so then restart the phone and check if it asks for credentials

These are line keys to enable the phone to handle multiple calls and you to be able to easily switch between them and perform attended transfers.
