[Freeswitch-users] FS does not honour sip-force-contact. Advice?

[Anthony Minessale]

the session timers are used to make sure a call is still alive by
sending a periodic re-invite to make sure the server is still there.
If the devices you are interacting with can't do it properly there is
not much to lose from disabling it.
