We are switching from a traditional line system to 3CX and using Yealink T46G phones. On our old system, there is a button for each extension that shows BLF plus is an intercom button with auto answer. So I can see if Tom is on the phone based on a red light being on or off, and if he's not on a call, I can push that button to intercom him. His phone beeps to announce an incoming internal call, and he can talk to me without doing a thing. When I hang up, the intercom call is terminated. On the Yealink phones with 3CX provisioning, it seems that the BLF gives me the extension status but does not let me intercom the phone. I found that if I program a speed dial *9<ext>, it gives me the same as our old "intercom" call, but doesn't show the extension status that BLF does. How can I combine BLF and an intercom/auto answer call? Thanks.
