If you're transmitting the CALLTOKEN IE in the initial NEW, that's what's
wrong.  You have to first send a NEW packet without the CALLTOKEN,
receive the response back (from source call 1), then retransmit the NEW
with the CALLTOKEN from that received packet appended to your NEW.

But a packet capture would definitely confirm that this is the problem.  The
fact that you're not receiving anything back suggests that the NEW
contained a CALLTOKEN that the receiving end could not validate, and
thus, no further contact was warranted.
