<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Is it worth here to say that this is also true if Asterisk is the callee?
Due to RFC4028 Asterisk will always honor the caller's refresher SIP session timer preference (if there's any) for who will initially handle refreshs when Asterisk is the callee.
And for completeness:
During already initiated (timer) sessions, Asterisk will always honor the other endpoints's refresher preference if it's received in any subsequent SIP Re-Invite request - regardless of wether Asterisk is the caller or the callee, or wether Asterisk is currently the refresher or not.

<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;">From the issue:
The SIP session timer mechanism contains a mandatory 'refresher' parameter (included in the Session-Expires header) which is used in the session timer offer/answer signaling within a SIP Invite dialog. It looks like asterisk is interpreting the uac resp. uas role only as the initial role of client and server (caller is uac, callee is uas). The standard rfc 4028 however assigns the client role to the ((RE)-Invite) requester, the server role to the ((RE)-Invite) responder.
This patch has Asterisk track the actual refresher as "us" or "them" as opposed to relying on just the configured "uas" or "uac" properties.</pre>
