214 Matrix PRASAR UCS System Manual
For PRASAR UCS upto 999 SIP Extensions can be registered with the system. PRASAR UCS supports
IPv4 Addresses only for registering Extended IP Phones
• Select the Use SIP Extension check box to enable the SIP extension. By default, it is disabled.
• In the Name field, enter a name for the SIP Extension, which may be the name of the person who will use
the SIP Extension or the name of a Department. The name you enter here will be displayed as the Caller
ID of the SIP Extension on the remote user's phone, when the SIP Extension user makes calls.
The name may consist of a maximum of 18 alphanumeric characters.
• Enter the SIP ID for the extension. The SIP ID is necessary for registering the SIP Extension with the
Registrar of the system. It is the number with which you can call the SIP Extension. Any extension user of
the PRASAR UCS can call a SIP Extension by dialing the SIP ID assigned to the SIP extension. SIP ID of
each SIP Extension must be a unique number string of a maximum of 6 digits. Any combination of digits
from 0 to 9 and the characters * and # are allowed.
You cannot assign the same SIP ID to more than one extension.
To assign SIP IDs according to your preference and requirement to a range of SIP Extensions, see
“Assigning Access Codes to a Range of Extensions”.
By default, the SIP IDs are Blank.
The SIP ID will be set to default value (blank), when you restore the default settings of the system.
•In Authentication ID, enter the number which you want the system to use for user authentication of the
SIP messages received from the SIP Extension. You cannot keep this field blank and it must be unique for
each SIP extension. The number may be a string of maximum 6 alphanumeric characters. All ASCII
characters except < > and “ (double quote) are allowed. Default: Blank.
•In Authentication Password, enter the password manually or click Generate to automatically generate a
unique password. This password will be used by the system to authenticate the SIP messages received
from the SIP Extension. To avoid unauthorized access, we recommend you to change the password
regularly. Make sure it is strong and is kept confidential. When the password is entered manually, the
password must:
• be of minimum 6 characters and can be a maximum of 12 characters.
• include atleast one upper-case, one lower-case, one number and one special character.
• all ASCII characters (except Percentage %, Hash #, Equal to =, Plus +, And &, Backslash \, Less than
<, Greater than >, Apostrophe ’, Double Quote " and Space) are allowed.
Default: Blank.
To provide additional security, when the Authentication fails 10 times consecutively due to wrong
Authentication ID / Authentication Password, the system will blacklist the IP Address and Port for
registration of this SIP Extension. However, you can remove the IP Address from the Blacklist IP
Address list. See “Black List IP Address - SIP Extensions” for more details. This activity will be logged
in the “System Activity Log” as well as “Simple Network Management Protocol (SNMP)”.
Make sure you note down or copy the Authentication Password in a confidential file.
