[SR-Users] rtpproxy and IP6 in c= line

Hi, Is there a flag in the rtpproxy module to force a change of the IP protocol field? When a call comes from an IPv4 endpoint and you do the bridging to IPv6, then the c= and o= lines contain the IPv6 address, but the address family is still IP4 (e.g. "c=IN IP4 10.10.8.22" becomes "c=IN IP4 fe80::1"). In case of bridging from IPv6 to IPv4, the field is correctly set to IP4 though (e.g. "c=IN IP6 fe80::1" becomes "c=IN IP4 10.10.8.22"). Is there something special to be taken into consideration? I couldn't find any hints in the rtpproxy module that it tries or would try to set that correctly (kam-3.1.5). Andreas
