Call Forward Feature Configuration
After you choose a call forward mode, you can configure call forward feature for all lines or specific lines. It depends
on the call forward mode (T30P/T30/T19(P) E2/CP920 except):
l
Phone (default): Call forward feature is effective for all lines.
l
Custom: Call forward feature can be configured for a specific line or multiple lines.
Note: Forward mode is set by the parameter “features.fwd_mode”.
Yealink phones also support call forward on code and off code to activate and deactivate server-side call forward
feature. They may vary on different servers.
Tip: You can set a DSS key as a Forward key, and specify a contact you want to forward the incoming calls to for this key.
For more information, refer to DSS Keys.
