Can anyone ell me if they've had experience on the continent with caller ID on analog POTS lines? Here in France, we currently do not have it enabled on any of out lines, but I would consider paying for it if I thought * via X100p cards would be able to detect it properly. I know for example that when people are calling us from the US or from London CID is not captured by France T?l?com, because we have a free service here where you can call a number to see if you missed any calls. Are the technical "specs" of CID different all over? Comments, experiences please?

Take a look at http://www.ainslie.org.uk/callerid/cli_faq.htm Lots of info there....

Some carriers remove the caller ID on international calls, some still send it. You might find if you are called by someone different in the UK you do get to see it! Also, the 'exchange' based caller id readout systems tend not to read out international caller id, but there are cases where the caller display devices would do so. Linus

But foreign carriers may use strange "path" in call routing, and may not be able to be able to send proper caller id. Basically, you will only see it if the foreign caller has direct SS7 connectivity. Otherwise, the foreign carrier is probably forwarding the call via some PRI, and often can't hide himself without hiding the original caller as well.> Are the technical "specs" of CID different all over? Comments, > experiences please?CID, at least in France, exists in two flavours : - carrier guaranteed, called NDI in France - user provided (and thus, not guaranteed by the carrier), called NDS in France On ISDN, the (french) carrier will usually provide both (out of which Asterisk will usually use the NDI). On POTS, France Telecom will usually forward the NDS if it looks correct (9 digits without leading 0), the NDI otherwise. International CID is usually carried in E.164 format (and may, or not, be dialable, depending on your local private exchange configuration). -- Nicolas Bougues Axialys Interactive
