[cisco-voip] CallerID conundrum...

[Jeff Behl]

when calls are made from a voip phone to a Cingular or AT&T cell phone, 
the callerid shows up just peachy.  when made to a Verizon phone, the 
recipient gets "Unknown Number".  my router shows:


voicegw-1.corp#sho isdn active
--------------------------------------------------------------------------------
                                 ISDN ACTIVE CALLS
--------------------------------------------------------------------------------
Call    Calling      Called       Remote  Seconds Seconds Seconds Charges
Type    Number       Number       Name    Used    Left    Idle 
Units/Currency
--------------------------------------------------------------------------------

Out  80569xxxxx     698xxx                     0 Unavail   -          0


(numbers x'd to protect the innocent)

so I'm thinking that i'm doing everything right from the CM/router side. 
  can anyone shed any light on why some providers would have this number 
show up as unknown??

any help greatly appreciated...
