[SR-Users] DISABLE SDP MEDIA STREAMS

Hello kamailio community, i know its an unusual query but i would like to know if there is a cleaner/proper.right way to disable some (or all) media streams in SDP. i have come with a solution by sdpops module with subst_body function like this. route[SDP_DISABLE_UNAUTHORIZED_MEDIA]{              # disable text,media and video media streams       subst_body('#^m=(video|text|audio)[ ]+[0-9/]+(.*)$#m=\1 0 \2#ig');       # update originator ip address       subst_body('#^o=([^ ]+)[ ]+([^ ]+)[ ]+([^ ]+)[ ]+([^ ]+)[ ]+([^ ]+)[ ]+([^ ]+)$#o=\1 \2 \3 \4 \5 7.7.7.7#ig');       #                        1                2                2            4              5          6       #                        name        sid            snumber    network net-type    addr       # update connection ip address       subst_body('#^c=([^ ]+)[ ]+([^ ]+)[ ]+([^ ]+)$#c=\1 \2 7.7.7.7#ig');       #                        1         2         3       #                       network net-type      addr       #remove all media attributes       sdp_remove_line_by_prefix("a=fmtp");       sdp_remove_line_by_prefix("a=X-");       sdp_remove_line_by_prefix("a=rtcp");       sdp_remove_line_by_prefix("a=ssrc");       sdp_remove_line_by_prefix("a=sendrecv");       sdp_remove_line_by_prefix("a=sendonly");       sdp_remove_line_by_prefix("a=recvonly");       sdp_remove_line_by_prefix("a=inactive");         sdp_remove_line_by_prefix("b=");        } is it the right way to do it. if not can someone provide me an alternative solution. Thanks :)
