You have several scenarios in the issue I opened in asterisk bugtracker. It's
not about who negotiates to be refresher, Asterisk won't honour that in any
case. All the scenarios I tried are broken in different ways.

Neeed to retest some day and check what oej says in the ticket, but I'm pretty
sure it wouldn't solve anything as asterisk session timers are known to be
broken since 1.6.
