<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;">Olle suggested on https://reviewboard.asterisk.org/r/2173/ a better method for adding the Require header to outgoing responses. I've used the same method used in his darjeeling-prack-1.8 branch here. The tests still pass properly.</pre>

<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;">This patch makes it so Asterisk adds Require: timer when appropriate when sending INVITE responses.
If session timers are in use, then there are two situations under which we'll add the header:
1) We are sending a 200 OK with a Session-Expires header that has a refresher parameter of "uac"
2) We are sending a 200 OK with a Session-Expires header that has a refresher parameter of "uas" and the INVITE to which we are responding had a Supported: timer header in it.
This patch also introduces another change. Prior to this change, the only way we would add a Session-Expires header in an INVITE response was if the inbound INVITE had a Supported: timer header in it. Now we always add this header if Asterisk using session-timers=originate. This is based on a table in section 9 of RFC 4028. It indicates that if the UAC does not support Session-Timers but the UAS does, then the UAS should send a Session-Expires header with a refresher parameter of "uas".</pre>

<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;">Tried the following three scenarios that should have resulted in Asterisk sending a 200 OK with a Require: timer:
1. INVITE with refresher=uac
2. INVITE with refresher=uas
3. INVITE with no Session-Expires but with Supported: timer
I also tried the following scenario that should result in a 200 OK with a Session-Expires (refresher=uas) but no Require: timer header:
INVITE with no Supported: timer header present.
I plan on turning this into a testsuite test as well.</pre>
