Ship it!


I've given a ship it! on this because nothing on this review is actually "wrong". These are merely suggestions.


/trunk/channels/chan_sip.c

    This all certainly works, and I'm not going to say this *can't* go in like this, but there are some functions that can help you out here to make things a bit simpler.
    
    s = ast_strip_quoted(s, "\"");
    if (sscanf(s, "%2d", &ani2) == 1) {
        ast_channel_caller(chan)->ani2 = ani2;
    }
    
    The only caveat to this approach is that ast_strip_quoted() modifies the string that you grabbed from the SIP request, so you'd need to change the top line of this function to
    
    char *from = ast_strdupa(sip_get_header(req, "From");

> Add ANI2 / OLI parsing for SIP.  The patch checks the "From" header during the handle_request_invite() function for the presence of "isup-oli", "ss7-oli", or "oli" tags.  If present, the up-to-2-digits following the equal sign in the tag are set on the channel's caller structure in the "ani2" int element.
