Isdn card


I’ve a ISDN line (in Spain of ONO provider) connected to a Network Termination for ISDN Basic rate Access (NT1Q from sphairon … -nt1q.html).

From there connected to a ISDN CARD:

Configured in asterisk with dahdi

[quote]ubuntu*CLI> dahdi show channels
Chan Extension Context Language MOH Interpret Blocked State
pseudo default default In Service
1 from-pstn default In Service
2 from-pstn default In Service

when a try to make a call exten => _X.,1,Dial(DAHDI/1/${EXTEN},)
i get the following message:

[quote] == Using SIP RTP CoS mark 5

any tip ??

Looks like you have the card configured in Point to Multipoint mode. Try changing to Point to Point mode. Also I see you have various different groups specified (0,12 and 63). Do you need these?
