<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">ASTERISK-24376 was created because at SIPit there was confusion about how to get remote attended transfers to work properly when using chan_pjsip.
To address this, I investigated the code and discerned what the intended way to perform a remote attended transfer is. I documented my findings on the following wiki page: https://wiki.asterisk.org/wiki/pages/viewpage.action?pageId=31096903
Please review the wiki page to ensure it makes sense.
While setting up a remote attended transfer, I came across a couple of minor issues. The following bug fixes are attached on this review:
* When sending an INVITE with a Replaces header, the Replaces header was malformed. It had the word "Replaces" twice.
* There was an error message that made it sound like external_replaces was a context being searched for, when it's actually an extension. I changed the log message to be more clear.</pre>

I'm in the process of writing a testsuite test but am fighting with PJSUA at the moment. Since I am going on vacation for a couple of weeks, I felt I should go ahead and get this review posted now. You'll see a testsuite review go up sometime at the start of 2015. Happy Holidays!</pre>
