RE: [asterisk-users] Diva Server, chan_capi and tone detection
This would require a change in chan-capi. To get the extended tone detection indications, additional request/parameter via CAPI must be issued. First, thanks for your reply. Do you have the CxDtmf.pdf document, from Eicon ? If I understand good, you have to enable DTMF facilities 248, 249 and 250, and then you receive DTMF code for tone detection : 0x81 for unidentified ton detected 0x80 for end of signal detected 0xC9 for human speech detected Etc... Another thing is, how do you want to get these indications for use in your dialplan? So, with DTMF code, you could handle it like for fax : redirect to extension vad or something ...

Yes.
If I understand good, you have to enable DTMF facilities 248, 249 and 250,
and then you receive DTMF code for tone detection :
0x81 for unidentified ton detected
0x80 for end of signal detected
0xC9 for human speech detected
Etc...
I didn't have a closer look into the values and commands yet, but basically
that should be right.
Another thing is, how do you want to get these indications for use in
your dialplan?

vad or something ...
That would mean to add for each of these signals an if {} to chan-capi
source. Not very nice, but will work.

[asterisk-users] Diva Server, chan_capi and tone detection
Hi all, I have a Diva Server V-BRI-2 card, which support, as written in reference guide: Extended tone processing (human talker detection, generation and detection of country-specific tones) I would like to detect human speech and fax tone with asterisk. I think that the diva card transmit a DTMF code when detecting voice, but chan_capi doesn't receive this DTMF code. I verbose it more, displaying all DTMF received, and only DTMF code CNG is received. Did you know how I can enable this detection (see DivaReportTones in Diva Server SDK) or how can I receive this DTMF in chan_capi ?
