Objective
The Shared Line Appearance (SLA) feature helps users share external lines in VoIP, ISDN, PSTN and so on. It also helps monitor the status of the shared line. When an outgoing call is made by the user, all members in the SLA group are informed about the call and will be blocked from this line appearance until the line goes back to idle state or the call is put on hold. When an incoming call is received, all the members are informed of it and may join it depending on the line appearance linked with the SLA extension.
The objective of this document is to show you how to configure the shared line appearance for extensions in Advanced Mode on SPA9X2 Series IP phones. This feature is present only in the Advanced Mode.

Step 1. Log in to the web configuration utility and choose Admin > Login > Advanced > Ext1 for Advanced Mode.
Step 2. Choose a desired share extension from the Share Ext drop-down list. There are two options: Private and Shared. The default is Private.
• Private — The extension does not share any calls and it does not use Share Call Appearance setting which is available in the phone tab.
• Shared — The calls will follow the Share Call Appearance feature on the phone tab. This feature makes two telephone icons appear near the line button to show that the line is shared. LCD's that share line appearances indicate that the share extensions is in use.
Step 3. Enter the shared user ID in the Shared User ID field. This indicates the user ID which is shared by all users assigned to the shared line. The default is blank.

SIP uses a SIP Proxy to perform many call setup functions. These proxy servers are used to route requests, authorize, and authenticate services to the users. The default value is 3600.
