 <pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'd make a note in the UPGRADE file that the SIPREFEREDBYHDR is now set with inheritance in chan_sip automatically. It's a small change, but it's still a behaviour change that people may not expect (or may have been working around for some time)</pre>

* Automatically put the Referred-By header in the outgoing INVITE message if the SIPREFERREDBYHDR channel variable is defined with a value.

* Made chan_sip.c:get_refer_info() set SIPREFERREDBYHDR for inheritance so chan_pjsip has a better chance to interoperate.

* Fixed refer_blind_callback() and refer_incoming_refer_request() to not modify the data in the pointer returned by pjsip_msg_find_hdr_by_name().  It seems wrong to modify that data since the calling routine doesn't own the buffer.</pre>
