Multiple Line Keys per Account
You can assign multiple line keys to associate with a specific account. The line keys are automatically assigned
with Line type from the first unused one (unused one means the line key is configured as N/A or the associated
account is not registered). All calls on this account will be distributed evenly among these line keys. It is useful for
managing a high volume of calls to an account.
When you assign multiple line keys to be associated with an account, you can configure the IP phone whether trans-
ferring a call or setting up a conference call on the current line key or on a new distribution line key.
It is not applicable to T19(P) E2/CP920 phones.
