Walter Doekes commented on ASTERISK-19942:
------------------------------------------

I ran into one today on my patched asterisk 10 (which should have the latest related patches).

The scenario went like this:

t0- asterisk called peer
t0- peer picked up
(no session timers)

t100- peer reinvited (on-hold)
t100- asterisk added session-timers (1800, refresher=uac, even though peer has no Supported:timer)

t200- peer reinvited (off-hold)
t200- asterisk added session-timers (1800, refresher=uac, even though peer has no Supported:timer)

t1968- asterisk dropped the call after 1800-32 seconds

> Tested different session-timer settings in sip.conf and asterisk does not honour refresher. It sends INVITE requests when it should not ot does not send any when it should. Depends on the configuration or scenario. Tested several scenarios to report. I'll add scenarios in notes.
