Feb 05, 2017
- Cisco IOS
Known Affected Releases
12.2(11)T 12.2(13)T1 12.3(1) 3.6(25)
Symptom: Very short amounts of DTMF, on the order of 20 milliseconds, may leak through in-band. This is likely to be a problem only where the network includes a DTMF detector that reports very short DTMF digits. Conditions: Where DTMF relay is enabled so that the DTMF digit should be removed from the voice path and relayed through the out-of-band path instead.
