Step 7 Enter a name for the trunk in the Name field.
Step 8 Click on the Switch drop-down menu and select the switch that the new trunk
will be associated with.
Step 9 Select the desired SIP Trunk Type radio button. There are two choices:
Dynamic - Select this radio button to provide more flexibility than a static
IP address. Note that all inbound calls will be accepted, regardless of their
IP address. If this is selected, you should use the authentication methods
available to prevent unauthorized callers from accessing the system.
Use IP Address - Select this radio button to enter a static IP address. This is
recommended if the systems are static and will not be changing IP
addresses often.
Step 10Enter the desired number of SIP trunks in the Number of Trunks field.
Step 11Click the Save button to store your changes.
F.2.2 Configure the SIP Device
SIP devices are the third-party telephones, gateways, terminal adapters, and other devices
that support the protocol. The ShoreTel phones do not currently support the SIP protocol.
With each of the SIP devices you will be using, you will have to consult the manufacturer's
instructions for specific instructions on configuring the device.
In a general sense, the configurations for each SIP device will be essentially the same, and
will require that the following pieces of information are entered:
IP address of the SIP server
IP address of the SIP registrar server
User name (identification for outbound calls)
User information (OSE or DID)
