[asterisk-users] NotifyCID to see who is calling for call pickup

If the phone of my colleague rings, I can see this with BLF-lamps on my 
Snom IP-phone. I would also like to see *_who_* is calling. I would like 
to see the external number on my screen so I can choose whether to 
pickup the call with BLF.

Therefore I have in sip.conf : notifycid = yes

With this setting on, I see on my screen : 10 --> 10

10 is the internal extension of my colleague.

But how can I see the external number that is calling in ?

I would expect to see : 10 --> 3221234567

3221234567 being the external number I would like to know about.

This is what Asterisk sends to my Snom IP-phone :

[Aug 11 16:37:56] Reliably Transmitting (NAT) to my.pub.lic.ip:1024:

<identity display="10">sip:10 at ip.ast.ser.ver</identity>
<target uri="sip:10 at ip.ast.ser.ver"/>
<identity>sip:10 at ip.ast.ser.ver</identity>
<target uri="sip:10 at ip.ast.ser.ver"/>

Where does Asterisk take the information to put into the dialog-info and 
how can I change it to display the external number also ?

Thanks !
