Summary:                    [patch] Session timer refresher incorrect
Description: 
Asterisk appears to request a refresher role swap relative to the original
refresher roles established in the initial INVITE that set up the
session/dialog, but does not actually perform the refreshes.  


GW -(1)-> Asterisk --> UA

(1)
In the 200 OK that establishes the dialog (the response to the initial
INVITE),
Asterisk sends the SST headers:

    Supported: timer
    Session-Expires: 180;refresher=uac

This establishes the UAC (the GW) as the refresher for this session. 
Asterisk sends a reinvite to the GW by canreinvite with the following
headers:

    Require: timer
    Session-Expires: 180;refresher=uac

This establishes the UAC (Asterisk ) as the refresher for this session. 
Asterisk does not, however, actually send any reinvites.

It looks like issue 18127.
