DAHDI ISDN bloquer (masquer) le numéro sortant

**F6HQZ** · 24/04/2013, 13h28

Bonjour,

Essayez de passer un CID bidon, non conforme, genre "ABCDE" (des lettres). Il arrive alors que certains opérateurs masquent le "faux numéro" présenté.

Cordialement,
Francois

Salut,

pour l'utiliser moi-même, SetCallerPres(prohib) est un moyen efficace de bloquer la présentation du CALLERID.

Code:

;International numbers
exten => _000Z.,1,NoOp(Outbound international call to number ==> ${EXTEN:1})
same => n,NoOp(${CALLINGPRES})
same => n,Set(CALLERID(number)=32321${CALLERID(num)})
same => n,SetCallerPres(prohib)
same => n,Dial(DAHDI/g11/${EXTEN:1})

Tu auras ensuite dans ton SETUP ISDN normalement :

Code:

Presentation: Presentation restricted, Network provided (35)  '32321NNNNN'

Et par sécurité, sur certains cas, je mets le CALLERID(num) à 0 (0000000000).

peu importe ce que j'indique pour "prohiber" le CLI le paramètre présentation est toujours avec la même valeur:
Presentation allowed, User-provided, verified and passed

Je pense que c'est peut-être un bug car la pas moyen de modifier ce paramètre de présentation.

Cordialement.

Chan_dahdi.conf & version DAHDI ?

**dose** · 24/04/2013, 16h17

Bon j'ai trouvé d'où vient le problème, tellement facile que c'est énervant.

En fait dans chan_dahdi.conf j'avais bien fait mon include de dahdi-channels.conf juste en dessous de [channels]

il y avait bien le paramètre de usecallingpres=yes plus bas dans la configuration mais il n'était pas pris en compte par Asterisk, car si usecallingpres se trouve après ma déclaration de channel ce dernier n'était pas pris en compte.

donc pour corriger le problème j'ai tout simplement modifié dahdi-channels.conf et ajouté usecallingpres=yes avant les channels

Code:

group=0,11
context=from-colt-isdn
switchtype = euroisdn
signalling = pri_cpe
usecallingpres=yes
channel => 1-15,17-31

Voilà une bonne journée de perdue juste pour ce paramètre à la mauvaise place...

Merci à tous pour vos propositions et bonne continuation!
