To allow system flexibility and cost efficiency, both Inter-Tel proprietary and other industry-
standard endpoints can be used with the Inter-Tel 5000.

IP endpoints using Inter-Tel Protocol (ITP) and Session Initiation Protocol (SIP) modes allow
users to communicate using the Local Area Network (LAN) and the public telephone network.
IP and SIP hard phones can be identified by the additional ports on the back, which are used
for inserting LAN and power connections. IP and SIP phones operate like digital phones
installed on the system except for the limitations listed on “IP Phone Limitations” on
