For internal calls, is there any way for the calling party to be notified that the called party is on the phone? I know that the calling phone could have the called phone as a BLF key and then the user would know before placing the call. But we have more extensions than we can add as BLF keys. It would be great that if the called party was busy, their phone would ring, but somewhere on the calling phone’s display it would say “User on the phone, ringing” or something like that.
We have a user who insists our old Inter-Tel system did something like that.
We currently use Yealink SIP-T48S phones.
