IP 8000 Conference Phone Application Note—Page 3
If this is an upgrade from previous ShoreTel versions you
•
may see a parameter named “Always Use Port 5004 for
RTP”, if so, you will need to disable this parameter (by
un-checking box), save the setting change. When enabled,
the SIP extension configuration will fail, it is also important
to note that this “one time” setting requires a system
restart (all servers first, then, ShoreGear switches followed
by IP Phones) to take effect. Once the server has been
restarted, this configuration parameter will no longer be
visible. This does not apply to new installations and
therefore the parameter is not visible (as shown in Figure 2).
Realm: The realm is used in authenticating all SIP devices. It
•
is typically a description of the computer or system being
accessed. Changing this value will require a reboot of
switches hosting SIP extensions. It is not necessary to
modify this parameter to get the IP 8000 conference phone
functional.
SIP session interval: Session interval value indicates the
•
session (call) keep alive period. There is no need to modify
the default value of “3600” seconds.
SIP session refresher: Refresher setting decides if the user
•
agent client or the user agent server refreshes the session.
Again, there is no need to modify the default value of
“Caller (UAC)”. This allows the IP 8000 to be in control of
the session timer refresh.
Switch Settings
Next allocate switch ports for SIP extensions. These changes
are modified by selecting “Administration” then “Switches”
in ShoreWare Director (Figure 3).

This action brings up the “Switches” screen. From the
“Switches” screen select the name of the switch to
configure. The “Edit ShoreGear …Switch” screen will be
displayed. Within the “Edit ShoreGear …Switch” screen
assign the Port Type Setting of one or more available
ports “100 SIP Proxy”(Figure 4), then save the configura-
tion change.
Note:
Each port provides proxy resources for 100 SIP
devices. Select as many ports as necessary.
