Cisco Bug: CSCur35598 - Malformed RFC2833 DTMF from IOS voice GW detected as 3 events
Sep 17, 2019
- Cisco TelePresence Server
Known Affected Releases
Symptom: A TelePresence Server may poorly detect badly-formed DTMF digits from some RFC2833 voice gateways and triple count the tones. Conditions: Only present in the 1.22 and 1.42 EFT releases of TS 4.1. This requires the sending DTMF device to have set the marker bit for each packet in a given DTMF tone, which is technically incorrect behaviour on the part of the sending device.
