[Asterisk-Users] CAPI and Extensions.conf Security problem

[Ignace CARIA]

Hi,

I've installing a AVM Fritz Card in my ASterisk Box

I've configured everything and its running perfectly.

The problem is that everybody is allow to call through it.

Explaination:

All users registered in Asterisk can make a call towards the ISDN network

But, everybody from the Internet, knowing the extension of CAPI in the 
dialplan, can call through my Asterisk to any phone number

Heeeeeellllllppppp mmmeeee please !


Thanks
Ignace
