Hello,
When using the SST module, refreshing in-dialog replies should work,
since the internal callbacks are called before the dialog module updates
it's timeout values.
Still, is you set the AVP in the onreply_route, that is known not to
work since the updating of timeout values is done before the
onreply_route is triggered.
indeed this is some sort of bug, that we intend to fix in the future
1.9 release, by triggering event routes for different events that occur
for the dialog module.
