Session Initiated Protocol
Planning and Installation Guide F – 5
• Multiple registrations of different numbers using the same IP address is not
supported as ShoreTel uses the last one received. (This is the case of Mediatrix
2102/1402; customers are expected to use only static trunks for these devices.)
• ShoreTel working with Static Trunks:
• OSE ranges might not work when different SIP devices are part of the same
trunk group. Customers are expected to create a dedicated trunk group for
each device that needs a static trunk.
• Customer must ensure that SIP devices work with static trunks. Routing
problems may occur when the same switch has a dynamic trunk group. These
devices should not be registered with the ShoreTel system.
• Director does not show information about the SIP devices registered in a switch.
This information can be accessed by telneting to the switch and issuing the
command print_register_table (applies only to dynamic SIP trunks).
• Groups of SIP trunks can be created at once but must be deleted individually (i.e.
one at a time).
• SIP devices need to work with dynamic audio ports. Customers are expected to
disable the parameter that forces the system to use only audio port 5004.
