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)
