We have thousands of Yealink phones purchased and in use, and now in V15 call forwarding on the Yealink stopped working. If a user needs to forward to another extension in the office it seems that this feature should work like it did in all previous firmware's with version 14. Please vote to get the Yealink T48G and T48S firmware fixed to work with version15. Support says it's not a supported feature. If Yealink is to be a supported phone the forward feature and features of the phone should work. We switched from Cisco to Yealink to get this feature working. I dont understand why it's not acceptable to resolve for all phones. It's a feature used in business environments for internal and external calls.
