Description
1 The IP Phone receives the IP address of the Connect Server (colocated
with the LTPS) through either DHCP or manual configuration.
2 The IP Phone contacts the Connect Server.
3
The Connect Server instructs the IP Phone to display a message on
its display screen requesting the customer IP Telephony node number
and TN.
4
The node number and TN are entered. The Connect Server redirects
the IP Phone to the Node Master.
5
The IP Phone contacts the Node Master. The Node Master redirects
the IP Phone to the LTPS.
6
The IP Phone contacts the LTPS.
7
If the IP Phone is valid, the LTPS registers it with the system.
Description
1 If the LTPS detects a loss of connection with one of its registered IP
Phones, it logs the event.
2 The LTPS then sends an unregister message to the system for that IP
Phone.
