Dear Ans,

Please check if the option "Disallow use of extension outside the LAN" is disable on extension configuration.
If that option is enabled then you need to check on black list and removed it from that list.
You can find more details here https://www.3cx.com/3cxacademy/videos/intermediate/configuring-remote-extensions/
https://www.3cx.com/docs/manual/configuring-ip-phones/

Please make sure that your Remote Location has Static NAT implemented as well to the phones and that the SIP port and RTP port range for each phone as specified in Extension Settings >> Provisioning tab is correctly forwarded to the IP address of each phone.
If you have multiple IP Phones on the same remote network configured with the same SIP and RTP ports, each phone must have a different SIP Port and a range of RTP ports must be configured per phone. To do this, click on the Provisioning tab, change the SIP and RTP ports and perform a re-provision of each phone from the Phones node.
Disable SIP ALG from the firewall.

Also make sure that you are using a certificate trusted by Yealink and that you are on the correct firmware
