asterisk users - Jan 2006 - Distinctive ring detection using SIP - Broadvoice addon line detection

Can * detect distinctive ringing on a SIP line?  The reason I ask is I have
broadvoice with an add on line.  It does not send any type of info that I
know of for the two separate lines so I can not determine which number is
ringing.  Broadvoice can however send distinctive ring tones so if I could
intercept that I could tell which line was ringing.  Or does anyone have any
other ideas to offer?

Last time I checked, Broadvoice sent the Alert-Info header in the
INVITE message. The main line does not have this header, an add-on
line does.
