CALLERPRES()=prohib_passed_screen not honoured over ISDN

system · November 19, 2010, 3:11pm

Hi,
I am currently setting up a AsterisNOW installation and trying to set “Presentation Restricted” over Q931 on outbound calls from SIP => Asterisk => ISDN (dandi)

I’ve figured out the Outbound CID needs to have “hidden” within the name field which is caught by:

[macro-outbound-callerid]
exten => s,n(hidecid),ExecIf($[“${CALLERID(name)}”=“hidden”]?Set(CALLERPRES()=prohib_passed_screen))

From the logs this is being caught and set, but the outbound call still sets : Presentation permitted, user number passed network screening when the ISDN passover is made.

I figure the important parts of the log below are:

Executing [s@macro-outbound-callerid:15] ExecIf(“SIP/100-000000a0”, “1?Set(CALLERPRES()=prohib_passed_screen)”) in new stack
Presentation: Presentation permitted, user number passed network screening (1) ‘0800’ ]

I have tried setting “hidden” within the trunk CID but can’t seem to block outbound CID - passing individual extension CID’s all works fine and presented correctly, so I have full control except on withholding the CID. My provider states they they will honour Presentation Restricted over Q931. So its appear that CALLERPRES()=prohib_passed_screen is getting cleared when passed through over Q931…

What am I missing?

Thanks guys.

Replying to myself here, but from further reading it would appear I need to set ‘usecallingpres=yes’ in zapata.conf.

As I’m using a TE121 single-span T1/E1/J1 card I presume this is instead needed within chan_dahdi.conf on a FreePBX box:

So will trying the following at earliest opportunity:

cat chan_dahdi.conf
; Copied from DAHDI Module of FreePBX

[general]

#include chan_dahdi_general.conf

[channels]
[color=#FF0000]usecallingpres=yes[/color]

; include dahdi groups defined by DAHDI module of FreePBX
#include chan_dahdi_groups.conf

; include dahdi extensions defined in FreePBX
#include chan_dahdi_additional.conf

Should this work on asterisk 1.6.2.14 ?

And for the benefit of anyone browsing the forums, this worked on Asterisk 1.6:

[color=#FF0000]> Calling Number (len= 8) [ Ext: 0 TON: Unknown Number Type (0) NPI: Unknown Number Plan (0)

                      Presentation: Presentation prohibited, user number passed network screening (33)  '0800' ][/color]
