Hi, I am using FreeSWITCH 1.4.19 with openSIPS as front-end. OpenSIPS is configured to insert a double Record-Route in SUBSCRIBE before sending it to FreeSWITCH. When FreeSWITCH sends the NOTIFY to openSIPS, there is only a single Route; but it should contains two Route built from the Record-Route. Here are a copy of the messages. The top-down Record-Route has not been copied into the Route of the NOTIFY.
