Matrix PRASAR UCS System Manual 159
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
26
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.
• During an on-going conversation, if there is a second incoming call, the system plays beeps to indicate the
second incoming call. You can set the frequency of the Call Waiting Tone (for SPARSH VP248/VP310/
VP510) beeps as per your requirement. You can select from the following options:
• Off
• Beep Once
• Beep until Answered
Default: Beep Once
However, when an ongoing call is being taped or recorded, the call waiting tone for any new incoming call
will not be played.
• 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

By default, the SIP Message Options INVITE and SUBSCRIBE are enabled.
Make sure that the Authentication ID for the SIP Extension has been programmed.
