Yealink Parts Compatibility by Model
On Yealink phones, phone cords and hookswitch tabs generally follow the same compatibility groups as the handsets. This article lists the parts compatibility between Yealink phone models.
Yealink Phone Cord Compatibility
Any Yealink phones that share compatible handsets also have compatible phone cords. The main difference between phone cords is the length of the straight sections at either end. Otherwise, they are roughly the same length.
In practice, any standard RJ9 phone cord should work. If your cord is broken, you can use one from another phone or purchase one locally. The only issue you may notice is that a longer straight section may not fit cleanly into the channel on the back of the phone.
