« on: March 12, 2019, 12:00:17 PM »

Hi all, I have absolutely no knowledge on this product so if someone could school me I would appreciate. I have 6 mitel 6863 phones which I need to connect in an adjacent building, was working before but the firewall we have installed are blocking the ports to the Mitel.

has anyone got a ports list of these types of phones and the ports that are require to be opened? as I have mentioned they do not connect at all at this stage.  help is greatly appreciated
