[cisco-voip] Incoming CLI Unknown but shows up at bottom of display

[Damian Turburville]

Unfortunately we do not have a CUBE, the calls are delivered from our carrier via SIP to our SBC and then over a direct SIP trunk to CUCM6.
I just dont understand why the call shows as Unknown Number and yet the caller number is shown at the bottom of the screen (see attached photo)

Here are some of the SIP traces from RTMT (I have anonymised the data a bit)

Hi Damian,
 
A SIP debug on your CUBE can clarify which fields you are getting and then you could use voice class sip-profile to modify some sip headers on your CUBE to fix it.
This assuming you have  a CUBE controlled by you between the CUCM cluster and the provider. 
 
Lacking that you could pull the SIP traces from the CUCM cluster and have your provider send the appropriate fields.

Hi,
Bit of a weird one here. Recently transferred PSTN services to a SIP carrier, so incoming calls are now coming through a SIP trunk from an SBC. Incoming calls are showing up as "Unknown Number" but at the bottom of the display, just above the softkeys it shows
 the correct CLI. Any ideas?
CUCM 6.1
