Hello Panagiotis,

getting the at least the call-ind in headers of sip reply would be good, 
do it by chunks (I do not know other option), in gdb:

$ frame 7
$ print *(buf+100)
$ print *(buf+200)
$ print *(buf+300)
$ print *(buf+400)

Then more or less same to get the request:

$ frame 2
$ print *(req->buf)
$ print *(req->buf+100)
$ print *(req->buf+200)
$ print *(req->buf+300)
$ print *(req->buf+400)

$ frame 1
$ print *hf

Make sure you pick a core that gives a backtrace like:
(gdb) backtrace

Would be good if we get on irc together, if you have time, to do a more 
realtime debugging -- will be faster. Let me know if you can do it 
today. I am on #kamailio or #sip-router channels on irc.freenode.net 
with id miconda.

Thanks,
Daniel
