Avaya Communication Manager uses a special port for telnet sessions. To use the Telnet Cut-thru feature in Redcell Synergy you must modify the port. You can do this during the discovery process by creating a Telnet authentication object and entering port 5023. Alternatively, once you install Communication Manager, open it from the Redcell Synergy Resources screen, select the Authentication tab and create a new Telnet management interface with port 5023. When you initiate a Telnet cut-thru session, Customer Manager asks for an emulation type. Select type 4410.
