Known Affected Releases
Symptom: Calls to CUE autoattendent or other CUE applications using DTMF are terminated seemingly at random. Specifically, sometimes when CME sends DTMF in an unsolicited SIP NOTIFY request, CUE sends an error response with status code 500. CME reacts by terminating the call. Conditions: Unsolicited notifications (sip-notify) are used for carrying DTMF from CME to CUE.
