2. Receiver enters room and MiniBrick registers with UCoMServer via SmartBrick & UCoMProxy
3. UCoMCaller queries UCoMServer to determine MiniBrick’s presence & location.
4. UCoMCaller sends a “wakeup” request to MiniBrick via UCoMServer. The UCoMServer forwards request to UCoMProxy & Smart Brick.
5. MiniBrick powers on the Receiver

1. Receiver invokes uTalk and registers with UCoMServer according to step 1
2. Caller invokes uTalk to contact UCoMServer and determine if receiver is present and power on
3. If receiver is present If receiver is powered on then
Caller sends call request along with its IP address
to UCoMServer, which relays request to
receiver else
Caller sends a wakeup request to UCoMServer which wakes up

3. If receiver is present If receiver is power on then
Caller sends a call request along with its IP address to the UCoMServer, which will relay the request to receiver else
Caller sends a wakeup request to the
UCoMServer which will in turn wake up receiver
4. Receiver opens a connection to caller, and they talk in real-time using the infrastructure network
