DOD is not working in 1 crystal

[surya]

I have 9 crystals in my OXE system and we are running R9.1. I have a PRI with another PBX (Coral) with 300 channels. recently there is an issue where the users from one particular crystal cannot access the trunk where as users from all the other crystals can make the calls. Also, only outgoing calls to Coral PBX from OXE are affected and the incoming calls to OXE are fine. The issue is with 700 Analog extenions ( Crystal No 5) only. I replaced the nprae board, chekced the access code status, Public Network COS. All are looking fine. Please help me with this.
