Well, this is session-timer issue. Looks like they request session timers in
form of reinvite to be sent every 14 minutes or they drop the call. The weird
thing is that this feature needs to be *negotiated* between both endpoints. Not
every system support it.

The spce does indeed support session timers. 

In 2.4, please check that you have the following setting enabled in config.yml

sems.sbc.session_timer.enable

And please send us a 'ngrep-sip b host yourpeer' capture to check if the
reinvites are being sent and why the call is being disconected.
