Protocols and Ports
Table 4-20 describes required connections for IP endpoints. The IP network must allow the
endpoints to establish these connections for proper operation.
Table 4-20. Mitel IP Endpoint Ports
Connection Name Ports Description
Dynamic Host
Configuration
Protocol (DHCP)
67 and 68/User
Datagram
Protocol (UDP)
The endpoint uses DHCP to obtain its IP address, subnet mask, default
gateway, TFTP server, and ICP address. This protocol is for use on the
Local Area Network (LAN) only. It is not required to traverse NATs and
firewalls. It is optional if all network information is statically programmed.
TFTP 68 and 69,
20001/UDP
The endpoint uses TFTP to download firmware during the boot process.
The endpoint/source number port number may be random, but the Mitel
5000 destination uses the specified ports. The endpoint ships with the
port setting at 0 (recommended). When left at this setting, the TFTP tries
port 20001 followed by port 69.
MiNet 6800–6802/
Transfer
Connection
Protocol (TCP)
The MiNet protocol is for basic call control. The endpoint/source number
may be random, but the Mitel 5000 destination uses the specified ports.
Switch Application
Communication
(SAC)
3998 and 3999/
TCP
The SAC protocol is for endpoint applications and programmable
buttons. The endpoint/source number may be random, but the Mitel
5000 destination uses the specified ports.
RTP (Inter-Tel IP
Endpoint)
5004–5007/
UDP
Real-Time Transfer Protocol (RTP) is for streaming audio. The Mitel
5000 and IP endpoints use the specified ports to send to and receive
from the peer endpoint.
Each channel requires two port numbers: The even port number is for
the RTP protocol, and the odd port number is for the Real-time
Transport Control Protocol (RTCP) protocol.
The port number value in DB Programming specifies the endpoint base
RTP port range. The first audio channel uses the base port+2.
RTP (Mitel IP

50098–50508/

Module)
6004–6261/

RTP (Expansion
