Steps to Resolve “Account Unregistered” Error on Yealink T46S

1. Upgrade Firmware:

• Ensure your phone is running the latest firmware. You can download the latest firmware from the Yealink support portal.

2. Check Network Environment:

• Verify that the phone is properly connected to the network and can obtain an IP address. If the phone cannot get an IP address, refer to this guide.

3. Verify Registration Information:

• Ensure that the registration information (username, password, SIP server) is correctly entered. If the information is correct, contact your service provider to confirm if the Rport feature should be enabled. You can enable Rport by navigating to Account > Advanced > Rport in the web user interface.

4. Check Server Host:

• Use a PC in the same network environment as the phone to ping the server host (IP address or domain name). If the ping fails, the host is unavailable, and you should contact your service provider. If the host is available and it is a domain name, try setting the port to 0.

5. Server Limitations:

• There may be limitations on the server side, such as MAC address, IP, or User agent whitelist. Contact your service provider for assistance or try registering another confirmed available account to the phone.

6. Change SIP Server Transport:

• Try changing the SIP server’s transport protocol to TLS, TCP, UDP, or DNS NAPTR.

7. Collect Diagnostic Files:

• If the issue persists, reproduce the issue and collect the Diagnostic File (config.bin, pcap file, level 6 syslog file). Refer to this guide for instructions on collecting diagnostic files. Upload the tar files and create a ticket in Yealink’s ticket system.
