ISDN RELEASE - CAUSE

Post by mtcl » 05 Nov 2015 06:16

An OXE is connected to ISDN network by PRI access. On outgoing attempt, the call is released, as soon as the remote party answers. Alcate OXE sends a message "MANDATORY INFORMATION ELEMENT IS MISSING", but I can not figure out what is wrong. Need your help, guys. Thanks
