Example VoIP Screen 1
Registration
REGISTRATION shows a count of the attempted and successful
registrations of the device/line with the server. These numbers <should>
be the same but, they can be slightly off due to network loss and server
down times.
TO - Shows the IP:UDP port of the server with which the device/line last
attempted to register.
FROM - Shows the IP:UDP port for the server which the device/line last
received registration info from. These might be different because some
systems send registrations to one server and receive the response from
another.
Line
LINE shows the <display name> and SIP <name> for the line. Some
devices might not have a <display name>, in which case there is only
one line of text shown. This identifies the actual line (i.e. phone line).
Device
DEVICE shows the MAC address of the device and IP address:UDP port
used by the device for SIP purposes.
