Have you ever put in an Asterisk system and needed to change the user of a SIP Yealink phone? Someone leaves the company and another person wants that phone? Well, I had to do this the other day. Here is what I had to do.
1. Menu --> Settings --> Advance Settings (change to a static ip address, subnet mask, default gateway, vlan enable, and vlan ID) I had to change from one company to another, thats why I had to change the network settings.
2. Menu --> Settings --> Accounts (change the Name, Label, User (extension), userID (extension)
The default password is admin on the Yealink
