Could you please give me some information as starting point on this. I dont know for BELL standard, but in V23, there different ways of sending the CLIP : before the ringing signal and during the first silence between 2 consecutive ring signals.
By looking at the sequence, it seems to me as if the first one (CLIP before the ringing signal) is used. Again, I dont know in the BELL standard (but I guess it should be somehow similar), the need to be some signal (called TAS) sent to the TE to let him know the CLIP is coming (so that it can set the line impedance in order to receive it). So could you confirm that CLIP before the ringing signal is coded in openzap, and indicate which type of TAS is used and where is this part coded in openzap.

The bulk of this code for V23 as you can see is already there, we just need this troubleshooting as we have never tested it. If you can get a raw recording of the channel it will probably help in testing. As for the mod_say_fr, please file this on http://jira.freeswitch.org Mike On Jan 18, 2010, at 5:01 PM, <de...@thom.fr.eu.org> <de...@thom.fr.eu.org> wrote: Hello, First let me congratulate for this great software. I was trying to diagnose a problem with my analog sangoma card, and FXS port giving intermitent ringing and not sending CLIP. I could see the intermitent ringing comes from this line. zchan->ring_time = zap_current_time_in_ms() + wp_globals.ring_on_ms; Setting zchan->ring_time could solve my problem, so could anybody indicate how to configure ring_on_ms (preferably in an XML configuration) The second point about CLIP is more difficult. First, let me indicate that Im residing in France and therefore using carrier and phones complying to european standard. About CLIP, I could see the V23 standard modulating frequencies are being populated (in fsk_modem_definitions in fsk.c). However, in zap_channel_send_fsk_data in zap_io.c, I could see that the BELL standard is hardcoded. Replacing the modem type with FSK_V23_FORWARD_MODE2 (which by what I could read seem to apply to me), I could see no difference. As I could not find as much relevant information as I would like in V23 (apart from the frequencies for the FSK), I was wondering what were I could find some information that could help to fix this. I dont know exactly what carrier_bits_start, carrier_bits_stop and chan_sieze_bits refer to, but I could find in that document (http://www.cs-strumentazione.com/manuali_pdf/clip.pdf) that « The Channel Seizure is present only in FSK-V23 Protocol. It consists in a series of 90 to 300 alternate SPACE/MARK bits » Considering this, I guess that I should use the else branch in the test « zchan->token_count > 1 ». What does this token_count refer to and where should I set it. Im still trying to figure this out (and will of course contribute the result of all this), so any help appreciated. I also did a contribution to mod_say_fr (to take into account the specific french idioms in saying date and time). Could you please tell me how to contribute this ?
