[SR-Users] Help : Kamailio RTP Proxy Issue...

Hello , This is the first time to put a question on sr-users mailing list and i hope to help me to solve my issue...i'm following this post http://saevolgo.blogspot.com/2013/08/rtpproxy-revisited-kamailio-40.html to setup RTP Proxy for kamailio 4 but it's NOT working as predicted and i'm receiving this error message on asterisk... [2013-10-16 05:20:04] ERROR[3216][C-0000002c]: netsock2.c:269 ast_sockaddr_resolve: getaddrinfo("192.168.1.80192.168.1.80", "(null)", ...): Name or service not known [2013-10-16 05:20:04] WARNING[3216][C-0000002c]: chan_sip.c:10873 process_sdp_c: Unable to lookup RTP Audio host in c= line, 'IN IP4 192.168.1.80192.168.1.80' [2013-10-16 05:20:04] WARNING[3216][C-0000002c]: chan_sip.c:10464 process_sdp: Insufficient information in SDP (c=)... The problem is NOT at the asterisk side but at the proxy side...when kamailio rewrites the SDP message it adds the public IP twice in the "C" filed of the SDP message instead of only one time like this 'IN IP4 192.168.1.80192.168.1.80' this is because the scripte is calling rtpproxy_manage() in the routes TOASTERISK /FROMASTERISK and in MANAGE_BRANCH / NATMANAGE. It should be either or,not both....but i don't know how to do this since i don't have any scripting skills so if anyone can modify the config file in the attachment i will be thankful...
