Hello All,
Suddenly PSTN incoming calls are not working for perticular range of DID. When i dial the number from outside, the calls are dropping after giving busy tone, before busy tone im hitting 10secs of silence. Checked the followings:
1. Users partition is in gateway's CSS
2. There is no Translation pattern or route patteren for same DID.
3. Getting the error message "Mandatory information element missing" in Debug ISDN q931 and getting value 96 in "origCause_value" CDR.
Am i missing anything?, please let me know.
