Hi, what's your sipwise rtpengine version? I once encountered similar issue
when the call >60s not yet answered, not sure if the same bug, you may want
to upgrade your rtpengine.

https://github.com/sipwise/rtpengine/blob/b507e245b2356f8b965a2671ab5f19a4cac837b0/debian/changelog
  * [a6d9c78] MT#13067 fix premature call timeout for un-answered calls

rgds,
