Could some please confirm that this behavior is incorrect. I am seeing issues where it appears that asterisk is not following the Record-route on it's reply messages. Please let me know if you require any other information. Thanks Example: xxx.yyy.154.243(PSTN-GW) <--sip--> xxx.yyy.77.23(Asterisk) <--sip--> xxx.yyy.91.74(SNOM or SER proxy) <--sip----> xxx.yyy.165.201(ATA186) 1) Call place from PSTN to xxx9931211 2) Asterisk via rules in extension.conf sends call to xxx.yyy.91.74 3) xxx.yyy.91.74 sends call to xxx.yyy.165.201 which is registered as xxx9931211 4) Call completes fine and audio works 5) PSTN Hangs up and the sends a BYE to Asterisk 6) Asterisk recieves the bye and sends BYE directly to the UA skipping the proxy 7) Results is that the proxy never recieves a BYE Complete SIP Trace http://www.routerboy.com/sip2004041902.html Example of actual Record-Route issue: -Message 9 the Proxy sends a Record-Route to Asterisk and Message 10 seems to be built are return to the Proxy but not with the infomation from the Record-Route Statement.)
