Setup to answer one phone from another in group

[Yealink_Daniel]

Hi,

BLF key is not only allow you to monitor the status of the extension and transfer call but also allow you to pick up a call with a BLF key.
For example, if you configure a line key as a BLF key to monitor extension 100.
When someone call 100 and 100 is ringing, the BLF key LCD will illuminates frequent red, if you press the BLF key of 100 in this time, the call will be pickup via your IP phone, and 100 will stop ringing and turn to idle.
Maybe this is what you want, if my understanding is wrong, please kindly correct me.

Thank you.

Best Regards
