Hi,

Record routes in SUBSCRIBE is not honored in NOTIFY, In my case i am having 3 record routes in SUBSCRIBE, but only one i.e top record route is used for NOTIFY is causing routing issue. I am using freeswitch version 1.6.17 for testing.

Following is the trace for SUBSCRIBE and NOTIFY at freeswitch.
