•  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 the box and saving the setting. When enabled, 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, or may be grayed out. The 

default for new installations is disabled, thus the parameter is not visible (as shown in Figure 

3). 

•  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 reboot of switches 

serving as SIP extensions. It is not necessary to modify this parameter to get the SpectraLink 

handsets 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.
