lThe IPCC system consists of the voice gateway, service server, database server, file server, and terminal.
lThe eLTE system consists of the trunking dispatcher, core network, base station, and terminal.
lIPCC and eLTE are interconnected using a standard SIP protocol. The SIP trunk needs to be configured for both IPCC and eLTE. IPCC and eLTE are specified as the outgoing destination for eLTE and IPCC respectively. When a voice call is initiated from IPCC/eLTE, it matches number rules and routes the call to eLTE/IPCC. Then eLTE/IPCC finds the destination device and sets up the call.
