A trunk with many numbers but rendom EUREKA! [SOLVED]

A trunk with many numbers

I have a trunk with a hundred numbers associated with it, it’s called GNR in Italy … I can’t translate it in English, maybe someone by what it’s called? …

However I come to the point: I would like to come out with some numbers as needed, I tried with the asterisk API specifically AMI but for now nothing …

Has anyone already addressed the problem?

Not totally understanding what you are asking for but perhaps this context is what you can start with

grep -B 10 -A 4 "\[from-did-direct\]" /etc/asterisk/extensions.conf


(Itzik) #3

I don’t understand what your question is here.

Try writing in Italian and maybe @dsmaldone will be able to translate or help out.


(Claudio Pelosi) #4

Scrivo anche in italiano:

Ho un GNR che in pratica è un trunk con molti numeri

Il cliente vorrebbe uscire tramite questo trunk ma in maniera casuale, esempio

numeri:
XXX54770
XXX54771
XXX54772
XXX54773
XXX54774

uscire una volta con XXX54771 la telefonata dopo con XXX54774 quella dopo con XXX54772 e via cosi’…

I don’t understand Italian, but I think I know what your problem is. Do you use a SIP-trunk? Try a PJSIP-trunk which better supports multiple numbers…

Don‘t know if this works

I believe @claloano wants outbound calls to have a Caller ID chosen randomly from a list. If so, you can adapt this dialplan, specifically the [outbound-random-cid] part: https://gist.github.com/lgaetz/2b3d67a30f86a827121b004ec2f3024a

I’m curious to know what you refer to here, I can’t think of any pjsip exclusive features that support this claim.


(Charles Darwin) #7

I was wrong, of course. I just thought that I read somewhere that that’s one of the advantages of pjsip.
Here it says something about multiple servers…

That’s nice. Really helps orgs with offices in multiple locations. Thank you, Lorne!


(Claudio Pelosi) #9

Yes, in fact I have to go out with always different numbers starting from a list of numbers all on the same trunk
Perhaps the path indicated by Lorne Gaetz can work …


(Claudio Pelosi) #10

I am trying this context because it should do what I need, that is: go out with a random number among many of a trunk

[Outbound-random-cid]
; this context generates a random number and chooses from a list of fixed outbound caller IDs
; based on the random result

exten => s, 1, noop (Entering user defined context outbound-random-cid in extensions_custom.conf)
exten => s, n, Set (foo = $ {RAND (1,10)}); choose a random number between 1 and 10
exten => s, n, Noop (choosing random CID # $ {foo})
exten => s, n, goto ($ {foo}, 1)
exten => 1,1, set (CALLERID (number) = 01821985050)
exten => 2,1, set (CALLERID (number) = 01821985051)
exten => 3.1, set (CALLERID (number) = 01821985052)
exten => 4.1, set (CALLERID (number) = 01821985053)
exten => 5.1, set (CALLERID (number) = 01821985054)
exten => 6.1, set (CALLERID (number) = 01821985055)
exten => 7.1, set (CALLERID (number) = 01821985056)
exten => 8.1, set (CALLERID (number) = 01821985057)
exten => 9.1, set (CALLERID (number) = 01821985058)
exten => 10,1, set (CALLERID (number) = 01821985059)
; add additional lines as necessary

; this final line is required in order to send the call flow back to the calling gosub line
exten => _X!, n, Return

; end contxt [outbound-random-cid]

it’s not working for me I think because I don’t understand well what to insert in the first line:

exten => s, 1, noop (Entering user defined context outbound-random-cid in extensions_custom.conf)


(Lorne Gaetz) #11
[macro-dialout-trunk-predial-hook]
exten => s,1,noop(Entering user defined context macro-dialout-trunk-predial-hook in extensions_custom.conf)
; exten => s,n,DumpChan  ; uncomment for debug

; check if this is an emergency call, and if so bypass all customization. Emerg calls must use an outbound route with the
; Emergency option toggled
exten => s,n,ExecIf($["${EMERGENCYROUTE}"="YES"]?MacroExit)

; check if outbound channel started as an incoming call
; if call is from an inbound route don't change CID
; exten => s,n,ExecIf($["${FROM_DID}"!=""]?MacroExit)           ; FreePBX < 12+
exten => s,n,ExecIf($["${DIRECTION}"="INBOUND"]?MacroExit)    ; FreePBX 12+

; set random cid
exten => s,n,Gosub(outbound-random-cid,s,1)

; log outgoing CID and continue
exten => s,n,Noop(Call proceeding with Outbound CID: ${CALLERID(number)})
exten => s,n,MacroExit

; end context [macro-dialout-trunk-predial-hook]

(Claudio Pelosi) #14

I put the text in /etc/asterisk/extensions_custom.conf

Extension 10 is configured to use the Outbound-random-cid context

[Outbound-random-cid]
; this context generates a random number and chooses from a list of fixed outbound caller IDs
; based on the random result

exten => s, 1, NoOp (Call rendom)
exten => s, n, Set (foo = $ {RAND (1,10)}); choose a random number between 1 and 10
exten => s, n, NoOp (choosing random CID # $ {foo})
exten => s, n, goto ($ {foo}, 1)
exten => 1,1, set (CALLERID (number) = 01821985050)
exten => 2,1, set (CALLERID (number) = 01821985051)
exten => 3.1, set (CALLERID (number) = 01821985052)
exten => 4.1, set (CALLERID (number) = 01821985053)
exten => 5.1, set (CALLERID (number) = 01821985054)
exten => 6.1, set (CALLERID (number) = 01821985055)
exten => 7.1, set (CALLERID (number) = 01821985056)
exten => 8.1, set (CALLERID (number) = 01821985057)
exten => 9.1, set (CALLERID (number) = 01821985058)
exten => 10,1, set (CALLERID (number) = 01821985059)
exten => _., 1, Goto (from-internal, $ {EXTEN}, 1); assuming they press 0 for the front desk
; add additional lines as necessary

; this final line is required in order to send the call flow back to the calling gosub line
exten => _X!, n, Return

; end contxt [outbound-random-cid]

But it always makes me go out with the 01821985050


(Itzik) #15

This is not going to work.

See above solutions with using the predial hook


#16

Try

exten => s,1,Set(CALLERID(number)=0182198${RAND(5000,10)})
same => n,Return

(Claudio Pelosi) #17

Important attention!
Talking to the telephone operator I got this information:
To exit with any number from the group of numbers assigned, you must use the fromuser parameter
id parameter is not needed …
I actually configured a trunt with the fonuser parameter with a number and it worked!
Now the point is how can I use the fromuser in context?
And then can I make it rendom?


(Claudio Pelosi) #18

I tried this but I think I am writing nonsense …

[outbound-r2]
; this context generates a random number and chooses from a list of fixed outbound caller IDs
; based on the random result

exten => s,1,NoOp(Chiama rendom)
exten => s,n,Set(foo=${RAND(1,10)}) ;choose a random number between 1 and 10
exten => s,n,NoOp(choosing random CID #${foo})
exten => s,n,goto(${foo},1)
exten => 1,1,set(fromuser=01821985050)
exten => 2,1,set(fromuser=01821985051)
exten => 3,1,set(fromuser=01821985052)
exten => 4,1,set(fromuser=01821985053)
exten => 5,1,set(fromuser=01821985054)
exten => 6,1,set(fromuser=01821985055)
exten => 7,1,set(fromuser=01821985056)
exten => 8,1,set(fromuser=01821985057)
exten => 9,1,set(fromuser=01821985058)
exten => 10,1,set(fromuser=01821985059)
exten => _.,1,Goto(from-internal,${EXTEN},1) ; assuming they press 0 for the front desk
; add additional lines as necessary

; this final line is required in order to send the call flow back to the calling gosub line
exten => _X!,n,Return

; end contxt [outbound-r2]


(Itzik) #19

Are you using the predial hook?


(Claudio Pelosi) #20

no but it looks interesting…
In which file should I write to use predial hook?
I do not know him…


(Claudio Pelosi) #21

EUREKA!
solved!

[macro-dialout-trunk-predial-hook]

exten => s,1,NoOp(Chiama rendom)
exten => s,n,Set(foo=${RAND(0,9)}) ;choose a random number between 0 and 9
exten => s,n,set(fromuser=0182198505${foo})
exten => s,n,set(CALLERID(number)=0182198505${foo})
; add additional lines as necessary

; this final line is required in order to send the call flow back to the calling gosub line

; end contxt [macro-dialout-trunk-predial-hook]
