Thanks for the tip, but as far as I know, France basically uses the US system. I got CID working with almost no change when using the Linksys SPA -3102 VoIP gateway, but no such luck with the OpenVox card.

I guess there's something I got wrong in either zapata.conf or extensions.conf, but it's hard finding information.

have you try all options on cid issue? i.e cidstart and cidsignalling in zapata.conf.

to know what kind of cid signalling you are using, you use ztmonitor to record voice before line ring.

you can mail me the voice record file so i can help you on this issue.

The cid format is varing from Telco to Telco, it is not a strict "standard", different kinds of telecom switch use different standard as they like.
