It can be a classic BSC (osmo-bsc), but it also comes with a binary that is BSC/HLR/VLR/MSC/AuC/SMSC... in one (we call it osmo-nitb). In osmo-nitb we can generate Facility IEs for Call Control.

Do you have an update list of mobile phones with CNAP support?

Regards,

Burak

Not sending the number is okay as long as one could somehow send the calling number later, but that seems to be not possible...

In fact the device's phonebook has priority over the received calling name in the facility of the setup message. At least, this is how it is implemented in current cell phones. Actually, there is little to no possibility to solve the issue unless the network sends the CNAP information without sending the associated CLI number. That way the mobile is unable to identify the callee thus cannot override the received name with the stored one. Yes, we also observed the issue.

From the tests of that code with phones it appears that CNAP is not shown if the caller is inside the phonebook. Maybe it is something with the notifySS-Arg or the place (embedded in the Facility of a SETUP Message). I added CNAP creation and embedding code into OpenBSC (http://openbsc.osmocom.org/trac/).

See the bug report for enabling it in Cyanogenmod: https://code.google.com/p/cyanogenmod/issues/detail?id=2666 Also, CNAP is not new. Canada's Rogers cellular network has supported it for some time. Other carriers seem to not be interested as it allegedly costs 1/2 cent to implement per call, and there's (supposedly) no user demand for it, see this article (from almost 4 years ago :) ) for more: http://www.wirelessweek.com/Archives/2007/05/Who-is-Calling-My-Cell-Phone-/ CNAP support is included with Android (there’s quite a bit of code involving it), but is disabled by default (I haven’t a clue as to why).
