Hi list,
my proxy (yy.yy.yy.yy) receives a message like this:
BYE sip:12345678@xx.xx.xx.xx SIP/2.0 Record-Route: sip:xx.xx.xx.xx;ftag=875188d2;lr=on Via: SIP/2.0/UDP xx.xx.xx.xx;branch=z9hG4bK07cb.466d8587.0 Via: SIP/2.0/UDP ww.ww.ww.ww:5060;branch=z9hG4bK875196bf Route: sip:xx.xx.xx.xx;ftag=1056999653;lr=on
My ruleset is something like this (with the REGISTER logic pulled out) :
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% route { if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; };
force_rport(); if (!method == "REGISTER") { record_route(); }; if (loose_route()) { route(1); }; loopkup("location"); route(1); }
route[1] { if (!t_relay()) { sl_reply_error(); }; exit; } %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
I would expect the packet to leave my router, back to xx.xx.xx.xx :
BYE sip:12345678@xx.xx.xx.xx SIP/2.0 Record-Route: sip:yy.yy.yy.yy;lr;ftag=2873864 Record-Route: sip:xx.xx.xx.xx;ftag=875188d2;lr=on Via: SIP/2.0/UDP yy.yy.yy.yy;branch=zu83fdhDB8d.67235676.0 Via: SIP/2.0/UDP xx.xx.xx.xx;branch=z9hG4bK07cb.466d8587.0 Via: SIP/2.0/UDP ww.ww.ww.ww:5060;branch=z9hG4bK875196bf Route: sip:xx.xx.xx.xx;ftag=1056999653;lr=on
But the outgoing packet is :
BYE sip:xx.xx.xx.xx;ftag=1056999653;lr=on SIP/2.0 Record-Route: sip:xx.xx.xx.xx;ftag=875188d2;lr=on Via: SIP/2.0/UDP yy.yy.yy.yy;branch=z9hG4bK07cb.02005244.0 Via: SIP/2.0/UDP xx.xx.xx.xx;rport=5060;branch=z9hG4bK07cb.466d8587.0 Via: SIP/2.0/UDP ww.ww.ww.ww:5060;branch=z9hG4bK875196bf
Do you have any idea about what is going on ?
Thank you. Best regards,
