Chih-Weih, sorry but I think he's right. H.323v4 8.1.14 says:
"The endpoint shall use the destination information returned in ACF or LCF
instead of the destination information passed in the ARQ or LRQ. [...]
For an egress gateway, the destination information that appears in the
ACF will be used to address a destination in the GSTN (for example,
appearing in the Setup message sent to the ISDN)."

So I think our gk should return "1230190" instead of "123".
Don't you agree?
