Known Affected Releases
Symptom: Inbound fax failure. The terminating side does not see the page data arrive and as a result the terminating fax machine tears down the call indicating that the fax had failed. Conditions: When faxes come in and utilize DSP for analog to digital conversion (Analog, TDM, etc.) page data is seen to arriving at the gateway (from the perspective of a PCM capture) after the CFR is sent by the terminating fax device. The page data is not being packetized by the DSP and sent by the gateway to the terminating fax device. This results in the terminating fax device tearing down the call.
