226 Matrix PRASAR UCS System Manual
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 digits. All ASCII characters except < > and
“ (double quote) are allowed. Default: Blank.
Make sure the User ID configured in “Digest Authentication” does not conflict with the Authentication ID
configured above.
•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.
•In Call Appearances, define the maximum number
42
of simultaneous incoming calls that the SIP
Extension user should be allowed to receive. You can set up to 10 call appearances for a SIP Extension.
Default: 2.
When Call Appearance is set to 2, the SIP Extension can receive 2 calls at a time.
• Under Auto Sign-In, enter the Email ID of the extension user you wish to store. The Email ID can be a
maximum of 64 characters. The Email ID is used for various server features.
• Auto Sign-In parameters — Send Configuration Mail and Mail Status, are applicable only for
Mobile Clients — VARTA ADR100, VARTA AMP100 applications.
• The Send Configuration Mail button will appear only after you have enabled the SIP Extension and
configured the SIP ID, Authentication ID and Password.
• Under Authentication, enable Authentication of any or all of the following SIP Message Options by
selecting the respective check boxes:
• INVITE Request
• SUBSCRIBE Request
By default, the SIP Message Options INVITE and SUBSCRIBE are enabled.
42. The calls that are routed through the system will depend on the number of Vocoder channels available. The channels supported
depends on the license purchased. For details refer to “License Management”.
