Network wide Virtual Office
Network Wide Virtual Office is supported for the CS 1000 systems.
This feature enables a user to use any IP Phone within the network.
The Virtual Office feature provides a call service to travelling users who
want to use a different physical IP Phone (other than the IP Phone they
normally use). Users can log on to another IP Phone using their DN and
preconfigured Station Control Password (SCPW).
After logged on, users have access to their DN, autodial numbers, key
layout, feature keys, and voice mail indication/access that are configured
on their own home or office IP Phones. For example, if users go to another
office or to a different location within the same office, they can log on to any

When the Call Server ELAN network interface is reinitialized to
implement the configuration change, the IP Phones and gateway
channels registrations are unregistered on the Call Server. The Call
Server releases the calls. When the link is reestablished, the LTPS
synchronizes the call states and releases the active calls. Service is
interrupted during this reestablishment period and the following are
affected:
— New IP Phones cannot register.
— Registered IP Phones cannot establish new calls.
— The Voice Gateway Media Card faceplate displays S009.
After the ELAN link comes back up, the Line Terminal Proxy Server
(LTPS) re-registers the IP Phones with the Call Server and all service
is resumed.
If the codec list is changed, the Voice Gateway Media Card DSP might
need to be reloaded. For instance, one DSP image contains G.711,
FAX, and G.729A/G.729AB. The other DSP image contains G.711, FAX,
and G.723.1. If the user has a node configured with the G.729AB codec
and the user performs an administrative change to use G.723.1 (or vice
versa), the DSPs must be reloaded.
After the CONFIG.INI file containing the administrative change is
downloaded to a Voice Gateway Media Card, the card DSP are reloaded
as they become idle. For instance, if all DSP are idle on the card, the
new image is loaded to all of them at once. If one or more DSP have
active calls, the DSP is not reloaded until the active calls have been
released. This can cause some DSP to be reloaded later than others.
