Call drops when these extensions are reached from pstn and through an IVR post selection. Freeswitch recived a SIP 302 Moved from these endpoints, call are processed on sip_redirect_context but freeswitch first send a SOFIA DESTROY to forwarding extension (correct) and then KILL A-leg (IVR) with the following error: CoreSession::hangup It seems freeswitch does not keep alive a-leg in this scenario.
