Hi MAyur,
Your trance does not show the INVITE being route outside the LB (.19).
Even more there is a "Too many hops reply" back, suggesting that a loop
is created on the LB and the INVITE is never sent to the destination
(but keep re-routed back to LB).
When you do t_relay() in your script, place before it an xlog to see the
destinations:
xlog("sending out request to $ru/$du\n");
