  Hi guys!

 I can reproduce the problem - I think there is a bug: nathelper's (k) 
 sipping_rpl_filter function - which should absorb the replies - is not 
 executed on received replies.

 Maybe there is problem in general with the reply callback or maybe 
 there is a bug from consolidating ser's and kamailio's module interface?

 regards
 klaus
