the title says it all ^^
On my older PBX system (3CX) i was able to make an internal call and if it was busy i was able to choice to active this funzion or not.
Essentially i just want to be able to call someone in the office, if she/he is actually busy i press a button on my phone and then, ASAP the person is free, my phone will ring so i know i can call them back… is this possible?
i would assume that this is a configuration related to the phones and not to the FreePBX, but i really cant figure wich one it is!
Phone that i’m using are mainly Yealink TP 21 E2 (plus some snom300).
Thanks for your time and help,
