You have a Yealink phone and you want to delete the SIP account on it. However, you cannot find any configuration regarding this issue in the web interface. This can be confusing for many users. But don't worry, the solution is actually quite simple.
You can use the %NULL% parameter in the cfg file to delete the SIP account on Yealink phones. cfg file is a configuration file and controls many features and settings of your Yealink phone.
You can delete your SIP account by setting the following parameters to %NULL% in the cfg file:
account.1.display_name = %NULL%
account.1.outbound_host = %NULL%
account.1.outbound_proxy_enable = %NULL%
account.1.password = %NULL%
account.1.sip_server_host = %NULL%
account.1.sip_server_type = %NULL%
This process will delete all your SIP account information from your phone. However, if the %NULL% parameter does not work, you can create a support ticket at https://ticket.yealink.com/ . When creating the support ticket, do not forget to inform the Yealink support team about the cfg file and your firmware version.
