Lorenzo -
I've submitted a feature request with this patch (http://bugs.digium.com/bug_view_page.php?bug_id=0000052). Your patch isn't completely descriptive, since I still don't know how you set the hidecallerid value from within a dialplan. Can you explain a bit more, please? Have you submitted a disclaimer to Digium so this patch might be added if it's seen as a useful addition?
Linus -
Thanks for the specifications. Did you have a patch or comments on how this might be implemented in the code?

We did something like this in chan_zap at pri_call() time:
case SIG_PRI:
[...]
if (ast->callerid) { strncpy(callerid, ast->callerid, sizeof(callerid)-1); ast_callerid_parse(callerid, &n, &l); if (l) { ast_shrink_phone_number(l); if (!ast_isphonenumber(l)) l = NULL; } }
[...]
if (l) { pres = ast->hidecallerid ? PRES_PROHIB_USER_NUMBER_NOT_SCREENED : PRES_ALLOWED_USER } else pres = PRES_NUMBER_NOT_AVAILABLE;
if (pri_call(p->pri->pri, p->call, p->digital ? PRI_TRANS_CAP_DIGITAL : PRI_TRANS_CAP_SPEEC p->prioffset, p->pri->nodetype == PRI_NETWORK ? 0 : 1, 1, l, p->pri->dialplan - 1, c + p->stripmsd, p->pri->dialplan - 1, ((p->law == ZT_LAW_ALAW) ?PRI_LAYER_1_ALAW : PRI_LAYER_1_ULAW))) {
[...]
where hidecallerid is a new field we added in ast_channel structure and it's set by our apps... As far as we can understand this should be more compliant to the q931 specs. (and it works for us in Italy ;-)
my 2 cents, Lorenzo

l is set a couple of lines above. Basically l carries the nubmer so if there is no callerid in 'l' then we send this other flag 'callerid not available'.
You need to choose one of these flags: /* Presentation */ #define PRES_ALLOWED_USER_NUMBER_NOT_SCREENED 0x00 #define PRES_ALLOWED_USER_NUMBER_PASSED_SCREEN 0x01 #define PRES_ALLOWED_USER_NUMBER_FAILED_SCREEN 0x02 #define PRES_ALLOWED_NETWORK_NUMBER 0x03 #define PRES_PROHIB_USER_NUMBER_NOT_SCREENED 0x20 #define PRES_PROHIB_USER_NUMBER_PASSED_SCREEN 0x21 #define PRES_PROHIB_USER_NUMBER_FAILED_SCREEN 0x22 #define PRES_PROHIB_NETWORK_NUMBER 0x23 #define PRES_NUMBER_NOT_AVAILABLE 0x43
I think it might be PROHIB....PASSED_SCREEN but not sure. Check q931 specs.
