Theory of Operation
The ShoreTel IP930D base appears to the MGC (Media Gateway Controller) to look like as many as
four independent ShoreTel IP Phone 230 models. Each IP930D handset has a unique MAC address,
achieved by adding a “02-” prefix to the handset’s IPUI number.The primary IP address of the base
may be statically configured or obtained using DHCP and assigned to one handset. The remaining IP
addresses must be configured using the DectHandset configuration parameter.
Each base is limited to supporting four handsets; this limit ensures non-blocking service to all handsets
(when all handsets are on independent three-way calls).
IP 230 MGCP signaling received by the base from the MGC is translated by the base to a format the
IP930D handsets can understand; in the opposite direction, the base translates DECT signaling into
MGCP. Each handset on the base is handled independently.
