IP Phone is registered. This is useful when you need to identify which
card to enable a message monitor on, or to connect a sniffer to, when you
debug a particular IP Phone problem. You can also achieve this by using
the IDU command from LD 32 on the Call Server, if you know the TN.
If you enter a particular IP address or TN but no card responds with the
information, an error message prints after the "wait for card responses"
timeout expires.
The regType field indicates the type of registration:
•
Regular: default registration; non-branch office Internet terminal
registered with its "home" TPS (the TPS defined by the telephone
S1/S2 configuration).
• Virtual: virtual office registration; Internet terminal "home" TPS is
another system but its user has invoked the virtual office feature
causing the telephone to register on this TPS.
•
Branch: branch office Internet terminal registered at the main office.
The main office TPS displays this type of registration.
•
Local: branch office IP Phone registered at the branch office. Internet
terminal is in local mode; the branch office TPS displays this type of
registration.
You can check the Up Time to see if an IP Phone or group of IP Phones
is resetting (the Up Time is less than the other telephones). This may
indicate a network problem if a group of phones in a specific subnet reboot
at about the same time.
Ensure that the firmware version is the same on all IP Phones. Compare
the version shown to the output of the umsPolicyShow command.
An IP Phone MAC address is in the middle of the Hardware ID, separated
by dashes from the remainder of the Hardware ID.
A single letter indicates the NAT type detected for an IP Phone. The NAT
column value is valid when the State column indicates the telephone is
registered to the CS 1000. Possible values are:
C = Cone NAT
S = Symmetric NAT
U = Unknown: behind a NAT of unknown type (response received from
only ES1)
P - Pending: waiting on response from the telephone or the telephone
never received a response from ES1
" " (space) = the IP Phone is not behind any NAT (normal case)
IP Phones with NAT type S are unregistered from the CS 1000.
