Some days I get calls for IT consulting services on a last-minutes notice, those entail things like “Internet is down”, other times its issues with devices that “worked” fine all last week, but suddenly today it’s not.
On this particular day I received a frantic call from a new client at an accounting firm that had 50 Yealink VoIP phones dropping calls randomly. As I tried to enter the Yealink “Advanced Menu” to collect traffic and logs, we were presented with “Incorrect Password.” We tried every password the office knew of and nothing seemed to work.
After spending several hours trying to sort out the password issue, it occurred to me that I just try the good old “Factory Default Password Reset.” After Performing that task, I went into the “Advanced Menu” and entered the default password of “admin” but yet again I was presented with “Incorrect Password.” I tried a few more times using uppercase and lowercase variations, and even tried well-known passwords like six zeros and the famous “password.”
After multiple searches and several failed attempts, I decided on a different approach to re-cement the “Factory Default Password” by using a locally hosted server and a configuration file.
Follow along with me and watch how I reset a YeaLink VoIP phone to factory default password. In this video installment series, I will first reset the Yealink VoIP password, in a follow-up video I will go through the steps to hunt down those dropped calls and how I solved them.
