Priority
Each extension of the ETERNITY is assigned a Priority Level starting from 1, 2, 3... to 9, with '1' being lowest 
Priority and '9' being highest Priority. Whenever an extension (phone) with higher priority calls an extension with 
lower priority, a triple ring is placed on the called extension. To know more, read the feature description “Priority”.
1. Select a Priority from 1 to 9 for the SIP extension. Default: 5.
If this SIP extension is assigned to Operator, you may want to set a higher priority for this extension.
Personal Directory
1. Select a Personal Directory number from 01 to 50 that you want to assign to the SIP extension. Default: 
None.
A Personal Directory is a list of 25 frequently dialed numbers, each of which are stored by Index number 
(location code), Name and Trunk Access Codes (). The Personal Directory is necessary for using the 
features “Abbreviated Dialing” and “Dial By Name”. 
When a Personal Directory is assigned to an SIP, it must also be configured. The Personal Directory can 
be configured also by the extension user. Refer the topic “Abbreviated Dialing” for instructions on 
configuring the Personal Directory.
Time Table
1. Select a Time Table for the SIP extension. Default: System Time Table.
If you have not configured Time Table, you may do so now, by clicking the Time Table link. Define the 
working days, and the start and end time of the working hours for each working day.
