Block an incoming call from particular DID
Re: Block an incoming call from particular DID
You can see "A" before Calling number - for international calls and "B" for private calls.
You can disable this feature - System/ other system param/ external signaling param - item "Type of number Unknown used ".
Really calling number (in t3 trace) looks like 21 81 : 123456789 - where 123456789 calling number, 21 81 - byte 3 - where in some bits present call type (national, international), presentation allowed or not (user will see or not calling number) and etc.
One more time about call number in SD for calling/called filtering. I use the next way (f.e. Ext. callback translation - empty):
1) create Ext. callback translation DEF/0/ - you will see external number on your digital set - f.e. A91XXXXXXXX
2) now you can create Ext. callback translation (additional string, not delete DEF/0) like you want - f.e. A91/1/0 (basic number A1, delete 1, add 0). In this case you will see (if initial number starts from A91) 91XXXXXXXX (without A because we delete 1 digit). When you see this number like unanswered - you can callback, PBX will dial 091XXXXXXXX (we add 0 - f.e. ARS or TG seizure).
So, if you understand ext. callback translation - you easy can decide what you need to declare in SD.
1) Ext. callback translation only DEF/0 - in SD call number A91XXXXXXXX
2) Ext. callback translation A91/1/0 - in SD call number 091XXXXXXXX
3) Ext. callback translation A91/1/- - in SD call number 91XXXXXXXX

Block an incoming call from particular DID
Thank you for sharing such nice information here now i can block incoming call
Re: Block an incoming call from particular DID
Hi Vad and all,
Please help to me
1/ Incoming DID (3910 1234) - ext (1098)
2/ Translator / called filtered number 1098, entity 20, public rerouting: false
3/ And then, teleservice filtering 1098 (ISDN service is other), index 1, overflow to 7308 (this real ext for testing)
4/ Create Abbreviated Numbering (mean SD) by range, range number 0, abbreviated No 0, call number 2839435252 (I want to block this number)
But I stuck at step 4, I can't create SD by range. I tried to many times with many range number/abbreviated no but without success.
Maybe I missing something in previous posts in this topic ? Please correct me.
Thanks.

Re: Block an incoming call from particular DID
Usually you have Direct SD - in management declared f.e. index of 1st SD = 0, numbers of SD = 1000.
For SD by range (before SD creation) - you need to manage "range".
f.e. for Range 0 - declare - index of 1st SD=1000 and numbers of SD=100.
After this - you can create SD in range 0.
In another words about this management example:
- SD with index from 0 to 999 (1000 SD's) belong to "Direct SD"
- SD with index from 1000 to 1099 belong to "Range 0"
For SD by range (before SD creation) - you need to manage "range".
f.e. for Range 0 - declare - index of 1st SD=1000 and numbers of SD=100.
After this - you can create SD in range 0.
In another words about this management example:
- SD with index from 0 to 999 (1000 SD's) belong to "Direct SD"
- SD with index from 1000 to 1099 belong to "Range 0"

Dear Vad,
I continue
1/ Incoming DID (3910 1234) - ext (1098)
2/ Translator / called filtered number 1098, entity 20, public rerouting: false
3/ And then, teleservice filtering 1098 (ISDN service is other), index 1, overflow to 7308 (this real ext for testing)
4.1/ Create Abbreviated Numbering (mean SD) by range, range number 0, index of 1st abbrev.number: 1000, number of abbreviated numbers: 100, number of digits: 2
4.2/ Create Abbreviated Number 0, range number 0, call number 2839435262 (I want to block this calling number, I enabled T3 tool and saw "CALLING_NUMBER 1=12, 21 83 Num: 2839435262)
4.3/ Caller Number Filtering, range number 0, abbreviated 0, filtering index 1, routing number 7304 (spam call will been re-routing to this ext)
As result: spam call was routing to Attendant sets. I saw t3 log " This call is connected to 3910 0000 (Main DID)" . Note that 3910 0000 is defined routing to 0 (is attendant group). I tried to change DID 3910 1234 to 7304, worked. It mean this DID is OK. I don't know why this DID 3910 1234 re-routing to Main DID 3910 0000 ???
Could you please advise me something?

Re: Block an incoming call from particular DID
Not spam calls - routed to 7308?
Call number in abbreviated number depends of External callback translation.
F.e. if in Ext. callback translation you have Basic number 2 (or DEF), delete 0, add 0 - call number shall be 02839435262

Re: Block an incoming call from particular DID
A client is receiving possible fraud calls from from international numbers +49..........., how can i block all incoming calls from this international prefix
Re: Block an incoming call from particular DID
If you have a considerable amount of possible fraud calls from +49 numbers, then I would suggest requesting your service provider to do the blocking insteadjorgesveiga64 wrote: ↑10 Jun 2021 11:07 A client is receiving possible fraud calls from from international numbers +49..........., how can i block all incoming calls from this international prefix
