Configuring SCA Feature on the IP Phone 
You can configure a primary account on a IP phone and other alternate accounts on other IP 
phones. In a SCA Hybrid Key System scenario, you can automatically assign multiple DSS keys 
with Line type for a registered shared line on the phone (If auto linekeys feature is enabled). For 
example, boss and secretary share the account 4603, boss phone registers the primary account 
4603 (register name and user name are 4603) and assigns line key 1 and line key 2 for the 
account 4603, secretary phone registers the alternate account 4603_1 (register name is 4603, 
user name is 4603_1) and assigns line key 1 and line key 2 for the account 4603_1, third party 
phone registers the account 4604. For more information on how to register an account, refer to 
Registering an Account.
