Make sure you have configured the full SIP URI (for example: 12345@abc.com) of the unwanted callers in
the Blacklisted Callers Number List.
• enable the Reject Calls from Blacklisted Callers check box on the SIP Trunks and Mobile Ports on
which you want to apply this feature.
• select the Number List you configured as Black Listed Callers Number List.
For instructions, see the following topics under Basic Settings:
• "Handling of Incoming
• "Handling of Incoming Calls"
Now, whenever there is an incoming call on the SIP Trunk or Mobile Port you have applied this feature, the
SARVAM UMG will match the number with the Blacklisted Callers' Number list you have assigned. If the number
matches with any of the numbers you have blacklisted, the system will reject the call.
Make a list of numbers that you want to black list. Configure these numbers in a Number List. By default, Number
List 16 is assigned as the Black Listed Callers List for the Mobile Ports and Number List 11 is assigned as the Black
Listed Callers List for the SIP Trunks.
You may retain this list and configure all the numbers you want to black list in this list or you may configure different
Number Lists for different ports and assign the lists to the ports.
Each number string in the List can have a maximum of 24 characters. If the callers' number exceeds 24
characters, the first 24 characters of the number will be checked. If the first 24 characters of the callers'
number match perfectly with any of the numbers programmed in Blacklisted Callers List, the call will be
rejected.
Call Detail Record Filters
SARVAM UMG enables you to generate reports of Call Detail Records using different filters. You can generate Call
Detail Record report of calls made to specific numbers (Called Party Numbers) and calls received from specific
numbers (Calling Party Numbers).
When you want to sort calls by Called Party and Calling Party Numbers, you must configure a Number list for each
of these.
To generate Call Detail Records using Called Party and Calling Party Numbers as filters,
• make a list of Called Party Numbers and another list of Calling Party Numbers.
• configure a Number List with the Called Party Numbers and another Number List with the Calling Party
Numbers.
By default, Number list 01 is assigned for both Called Party and Calling Party numbers. You may retain
this list and configure Called Party and Calling Party numbers in this list, or you may retain this for Called
Party Numbers and configure another list number for Calling Party numbers. In this case you must assign
the list you configured to the respective filter.
