digium HW echocancellation - fax tone detection
...off ?
When I do a cat /proc/dahdi/1 for span 1 I see still the VPM450 entry
near the channel although this was a fax call with CED tone.
1 TE4/0/1/1 Clear (In use) (EC: VPM450M)
Greping through the source, i see only a CED tone detection
entry in:
static const struct dahdi_echocan_features vpm450m_ec_features = {
.NLP_automatic = 1,
.CED_tx_detect = 1,
.CED_rx_detect = 1,
};
Does it mean that CNG tone is not going to be detected ?
Does the CED tone detection routine also detect ANSam tone for Super G3 fax ?
Thanks
Regards
Hans
