Hi all i'm hopping you can help with the following problem i'm having. I setup an elastix pbx 1.5.2 with a sangoma a500d BRI card, the problem i'm having is when calling from Our Alcaltel PBX OMNIPCX 4400 to the DID number it seems like the ISDN does not pass the call through to the Elastix PBX, there are no incomming call traces or logs to trace what might be causing the problem be. The Alcatel and Elastix are not interconnected. But if i Dial the DID number from a Cell phone the call is passed from the ISDN to Elastix pbx. On the Alcatel there are 3 E1 cards and No ISDN's connected to the Alcatel. Can it be a sangoma driver issue or can it be the ISDN BRI NT that is not configured correctly. I have been struggling with this for almost a week now and luck is not on my side. Any help will be highly appreciated!!!!!!!!!!!!!!!!!!
