Not at this moment, but can be eventually added as t_reply_error(), as 
there is an internal variable holding that code.

Btw, after using t_relay() in this case, is better to use 
send_reply(...) instead of sl_send_reply(...), to clean the transaction 
gracefully in case the appropriate structure was created.
