It was not my fix :-)

  you can just use the sipcapture module from 3.3 together with 3.2, 
just recompile.

"unsupported family" says: this packet is not HEP.

kamailio is listening on the both interfaces, not sipcapture self.

you can make a trick, check in hep_msg_recieved() a destination port of 
the receive_info structure

something like this:

ri = (struct receive_info *)srevp[2];

if(ri->dst_port != 9060) return -1;
