Outbound calls to Denmark not working

Asterisk Asterisk Support
1

Hello Community,

We use Asterisk 11.13.1 . Carrier is Verizon. Origin of calls: USA
Issue: We are unable to place calls via Verizon to Denmark. Users in Denmark say they talked to their operator and were told they do not see any calls coming through.

We were told by Verizon to check our configs. So far we were asked to make 2 changes:
1st Change (Implemented): we were asked to change screening indicator value:
— Screening Indicator (0) reserved (for “user Provided, not Screened”) TO Screening Indicator (3) Network Provided—

2nd Change (yet to implement) to Change "Nature of Address (115) Non-unique national Number TO " Nature of Address (3) National significant number (i.e., 10D ANI/C SI)
We are yet to make the 2nd change.

Verizon did some testing and It appears that even in their “successful” call, they had “Screening indicator (0) reserved” so 1st change above is clearly not the issue.

Question to community: I do not know where or how to make this 2nd change. Which file to edit, where to look in Asterisk 11.13.1? or if the 2nd change will even help us with the issue.
a. How do i fix this issue where our calls are not delivered to Denmark?
b. Where do i find the file that Verizon is asking us to change? ( Nature of address (3) National significant number (i.e., 10D ANI/CSI) )

I believe you want:

; PRI Local Dialplan:  Only RARELY used for PRI (sets the calling number's
; numbering plan).  In North America, the typical use is sending the 10 digit
; callerID number and setting the prilocaldialplan to 'national' (the default).
; Only VERY rarely will you need to change this.
;
; unknown:        Unknown
; private:        Private ISDN
; local:          Local ISDN
; national:       National ISDN
; international:  International ISDN
; from_channel:   Use the CALLERID(ton) value from the channel.
; dynamic:        Dynamically selects the appropriate dialplan using the
;                 prefix settings.
; redundant:      Same as dynamic, except that the underlying number is not
;                 changed (not common)
;
; prilocaldialplan cannot be changed on reload.

However, I don’t use chan_dahdi, and support for hardware interfaces should generally come from the hardware vendor.
