[Freeswitch-dev] Openzap and CLIP

Here comes the patch. 

The patch fixes the CID for France (and
probably other european countries except maybe england where a specific TAS
has to be used), both for incoming calls and call waiting cases. 

anybody can try this patch with US hardware to verify the compatibility.

I added a new parameter in openzap.conf (modem-type defaulting to
FSK_BELL202) so that modulation can be specified in config. 

The patch
also adds the MWI functionnality on FXS ports (that meant to also patch
mod_voicemail), by using the MWI-Account parameter in directory set to
something like "openzap/x/y". 

Please comment on this, if any modification
need to be made.

I'm very happy to announce I could finally get this to work.

So far I only have a very dirty patch so I'll try to arrange this a
little bit, then I'll post it to the list. 

Does anybody have an idea on
how to make the CID feature configurable (for the different standards used
BELL/V23) ?

Hello François,

That lead me to think that maybe this is a non implemented feature
and maybe the data in fsk_buffer should be sent somewhere to the card.

Could anybody shed me some light on this.   

I am not terribly familiar
with the analog code, but ...   

The fsk buffer seems to be sent when
calling send_caller_id(), which is called from

In any case, there is not much places
where the modulated signal can be sent, everything goes down the file
descriptor of the channel via zap_channel_write(). As I said, is done
through send_caller_id() -> zap_channel_send_fsk_data() which sets the
write function pointer to zchan_fsk_write_sample() and is then called back
when calling zap_fsk_modulator_send_all().   

May be you should take a
look at src/testcid.c to learn about the API usage and src/zap_callerid.c
to see the implementation.
