Precautions:

(1) No matter whether the forwarding number is long-distance or short-distance, the format of dialing fixed telephone, local telephone, secretary desk and Ruyi call must have area code, and the mobile phone can directly input it.

(2) The calling number cannot be an international phone (including Hong Kong, Macao and Taiwan) or an extension number, and the digits of the transfer number cannot exceed 14.

(3) When user call waiting and busy transfer are set together, only call waiting will take effect, busy transfer will not, and the level of call waiting is relatively high.

(4) When roaming internationally, users cannot set the call transfer to other countries (excluding China) outside their roaming area, but they can set the call transfer to some countries or regions (depending on local network settings).

(5) Call forwarding to foreign phones is not supported.
