Hello.

I am not sure who to reach out to but our supplier said we need to return direcectly to Yealink.

I have a customer who was installed last october has since had 3 of there phones turn bad slowly, They said a couple have been bad from the beginning but they had spares they used instead..

Now they are looking to replace them.. How do we go about this.

Thanks,

Pls call 360-229-7166 ext101
