I have a T46S Yealink deskphone and 4 Yealink W56H wireless handsets. In my office, all the handsets can communicate with each other via intercom. Here is my problem: recently RC told me that the T46S phone and the W56H phones can not be set up to communicate via intercom with each other. Has anyone been able to set up an intercom communication between a T46S desktop phone and a 56H or 52h handset? If so, could you please share that with everyone?
