Virtual Office login failure (scenario 3):
• IP Phone A logs into IP Phone C and
establishes a call with IP Phone B. All three
IP Phones are registered with the same
Call Server.
• TLAN subnet failure occurs. IP Phones A
and B fail and IP Phone C does not fail.
• IP Phone C tries to log into its home TN
before IP Phones A and B go offline.
IP Phone C cannot log into its home TN if
another active IP Phone is logged on its TN.
IP Phone C can log into its home TN only
when the call register is released or becomes
PARTIAL REBUILT.
Refer to Virtual Office login failure scenarios 1
and 2 on page 83.
Network-wide operation — network TLAN
subnet failure:
• IP Phone A has an IP Peer call with a
remote user over a virtual trunk.
• IP Phone A’s TLAN subnet connection
fails.
• Active IP Phone A reregisters with the Call
Server when the TLAN subnet comes back
up.
The call is not lost.
The scenario is the same as if the far end
were a local IP Phone. See “TLAN subnet
failure:” on page 79.
Network-wide operation —
network Call Server warm start
• IP Phone A has an IP Peer call with a
remote user over a virtual trunk.
• The Call Server warm starts.
• Active IP Phone A reregisters with the Call
Server as the TLAN subnet comes back
up.
The call is not lost.
The scenario is the same as if the far end
were a local IP Phone. See “Call Server warm
restart:” on page 80.
