User's Manual

Account selection
There are a number of scenarios where you are prompted to select an account (for example,
logoff, per-account settings, programming keys).
The scenarios fall into the following two categories:
• Prompts where you must select exactly one account. If only one account is logged on,
the prompt does not appear. The IP Deskphone selects the single account automatically,
and immediately displays the next screen. Otherwise, the primary account is always at
the top of the list, and is highlighted when the prompt first appears.
• Prompts where an all or none option is available.
Pressing an account line key highlights the corresponding item in the account list. If no
selection is made in a certain amount of time, the prompt acts as if you pressed the Back
context-sensitive soft key, canceling whichever operation required selection of an account.
Feature dependencies and restrictions
The number of line keys on the IP Deskphone limits the number of accounts that you can
register simultaneously. The IP Deskphone is limited to six accounts. Connecting an Expansion
Module to the IP Deskphone increases the limit by 18, allowing for 24 registered accounts.
Additional Expansion Modules do not increase the limit further.
These are hard limits. Further restrictions may be imposed by the administrative policy. See
Configuration files.
Performance characteristics
Because the multiuser feature can allow the IP Deskphone to have multiple users logged on
to the IP Deskphone at the same time, the chances of numerous multiple calls increase. The
IP Deskphone can handle five simultaneous incoming calls at a time without any noticeable
impact. But as the number of simultaneous incoming calls increase, there is a noticeable delay
in ringing and updating the display to present all the calls to the user. It may take up to five
seconds for 10 simultaneous incoming calls, and this time increases as the IP Deskphone
receives more simultaneous incoming calls.
CS 1000: Several keys with the same DN on a TN
CS 1000 allows you to simultaneously make or receive a maximum of 2 calls. To overcome
this limitation you can configure several Multiple Call Ringing (MCR) keys with the same DN
