Mitel 6800 Series SIP Phone Release 4.2.0 Administrator Guide
4-31
ADVANCED NETWORK SETTINGS
You can set advanced network settings on the IP phone such as Network Time Protocol (NTP)
Time Servers, Virtual LAN (VLAN), and Quality of Service (QoS) using the Mitel Web UI or the
configuration files.
SIP AND TLS SOURCE PORTS
A System Administrator can configure the SIP and TLS source ports on the IP Phone.
Previously, the IP phone used default values (
5060
for UDP/TCP and
5061
for TLS). The two
new parameters for configuring the SIP and TLS source ports are:
• sip local port
• sip local tls port
You can configure the SIP and TLS source ports using the configuration files or the Mitel Web
UI.
After configuring these parameters, you must reboot the phone.
Configuring SIP and TLS Source Ports Using the Configuration Files
You use the following parameters to configure SIP and TLS ports:
• sip local port
• sip local tls port
For specific parameters you can set in the configuration files, see Appendix A, the sections:
• “Local SIP UDP/TCP Port Setting” on page A-30.
• “Local SIP TLS Port” on page A-31.
Note:
The available advanced network parameters via the IP phone UI are VLAN and
QoS only.
Notes:
1.
By default, the IP phones use symmetric UDP signaling for outgoing UDP SIP
messages. When symmetric UDP is enabled, the IP phone generates and listens
for UDP messages using port 5060.If symmetric UDP signaling is disabled, the
phone sends from random ports but it listens on the configured SIP local port. Refer
to
"Symmetric UDP Signaling‚" on page 29 for more information.
2.
The IP phones also use symmetric TLS signaling for outgoing TLS SIP messages
by default. When symmetric TLS is enabled, the IP phone uses port 5061 as the
persistent TLS connection source port. When symmetric TLS signaling is disabled,
the IP phone chooses a random persistent TLS connection source port for TLS
messages from the TCP range (i.e. 49152...65535) after each reboot regardless of
whether the parameter “sip outbound support” is enabled or disabled. Refer to
"Symmetric TLS Signaling‚" on page 30 for more information.
