asterisk users - Jul 2004 - isdn to sip callerID pass

hi,

I have a problem with passing caller id information from telco (isdn) to 
sip client (grandstream).
i see callerid in asterisk verbose console but on grandstream (sip) 
phone is just internal (own-gs) 101 number.
Isdn line is connected with hfc card and p2p , asterisk is latest CVS in 
extensions.conf i have:
 
exten => 2442242,1,Dial,SIP/101,r|T


and in console is this:

-- Executing Dial("Zap/1-1", "SIP/101") in new stack
    -- Called 101
    -- Accepting call from '4482333' to '2442242' on channel 1,
span 1
    -- SIP/101-b1e2 is ringing
    -- Channel 1, span 1 got hangup

and number on GS sip phone must be  4482333 but is  only  101 !
maybe i missed something?

thank you,
Tomaz
