[cisco-voip] ISDN to ISDN hairping on CME40

hi,

i want to allow an ISDN hairpin on a PRI with no success so far. I tried 
anything in terms of transfer system commands (full-blind, full-consult, 
local-consult) and i have a transfer pattern of .T in the config. But 
after dialing the last digit of my mobile number i always get a busy 
signal.

neither the debug voice dialpeer all or the debug voice ccapi inout 
command show anything while i'm dialing the digits of my mobile number, a 
sniffer trace shows that the digits are sent to CME.

does anybody have an idea if the isdn to isdn hairpinning is supported 
anyway and if so, what commands might be worth a try in my case?

thanks
mat
