[Freeswitch-dev] openzap information + mod_say_fr contribution

[Michael Jerris]

In regards to the CLIP.  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

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.
