Strange Problem with a T1 isdn with SBC
Hi, I have a strange porblem with a T1 PRI programmend like ESF,B8S.
Ihave 2 option 11C A and B connected with muxes only with DTI cards, one of the PBX A is in at different city and is connected to SBC lines with a T1 PRI, all the call get well to that PBX A and some DID are sent to the PBX B and all work fine, but some one detected when I received a call from a specific local Central Office, the call can not be send to the PBX B but if a ended the DID to a local extension of th PBX A the call get in a the set ring fine. I detected whe this happend a received a berarer cap of 3.1 khz.
Someone know something about this problem?
