Call Agent Controlled Mode for RFC 2833 DTMF Relay
Troubleshooting
This section describes general troubleshooting procedures related to the call agent controlled mode for
RFC 2833 DTMF relay.
General Troubleshooting Procedures
This section explains how to troubleshoot the following conditions:
•
•
Basic Call Cannot Be Established
Problem: A basic call cannot be established through the MGW.
Symptom: The CRCX message sent to the MGW results in failure.
Diagnosis: Determine whether the MGW supports CA-controlled RFC 2833 DTMF relay. (See the
MGW vendor documentation for information on MGW features.)
Resolution: If the MGW does not support CA-controlled RFC 2833 DTMF relay, set
dtmf-telephone-event-enabled=N in the QoS table associated with the endpoint.
No DTMF Relay Involving H.323 Endpoints
Problem: RFC 2833 DTMF relay does not work on the H.323 gateway or endpoint.
Symptom: DTMF tones do not go through.
Diagnosis: Determine whether the RFC 2833 payload configured on the H.323 gateway or endpoint
matches the payload configured on the Cisco BTS 10200 Softswitch.
Resolution: Ensure that the value of rfc2833-payload in the applicable h323-tg-profile or
h323-term-profile table is set to the same value as that on the H.323 gateway or endpoint.
