[SR-Users] rtpproxy-ng doesn't work with mediaproxy-ng

[Khue Nguyen Minh]

Thanks Richard. Now, rtpproxy-ng can work with mediaproxy-ng. But, I have
some error when run it. After rtpproxy-ng send SDP information to
mediaproxy-ng, it receive wrong IP. please see follow log:

And in SIP message I capture from network, IP address in SDP body become
0.0.0.0. The call setup success but I don't hear anything. When I hangup
this call, module rtpproxy-ng segment fault, and this is call stack:

#0  bencode_string (bencbuf=0x7fffb6206760, msg=0x7fd617cb13a0,
op=OP_DELETE, flags_str=0x7fd617cd5f90 "fox", body_out=0x0) at bencode.h:349
#1  bencode_list_add_string (bencbuf=0x7fffb6206760, msg=0x7fd617cb13a0,
op=OP_DELETE, flags_str=0x7fd617cd5f90 "fox", body_out=0x0) at bencode.h:407
#2  rtpp_function_call (bencbuf=0x7fffb6206760, msg=0x7fd617cb13a0,
op=OP_DELETE, flags_str=0x7fd617cd5f90 "fox", body_out=0x0) at
rtpproxy.c:1191

Please help me fix it.

Thanks
Khue.
