I can establish a ISDN call from South Africa to Sweden but not from Sweden.
I have found that my layer 2 is TEI_ASSIGNED AND NOT MULTIPLE_FRAME_ESTABLISHED
This is my configuration on the Sweden 1750 router.

The problem is with the layer2 establishment
with the net3 switch. You should confirm with
your carrier that the switch is indeed net3
(although that should be correct, given that
you can receive calls). Note that is
Europe it is often the case to have the
TEI's assigned during a call; in this
case you would need the command "isdn tei
first-call" (power-up is the default). You
might try this command, then enable "debug
isdn q921" and try to make a call. What
should happen is the TEI remains unassigned
until a call attempt is made, then we
negotiate the TEI, but only for that
call.
