Truth be told, I have never ever tried freeswitch with sofia mod, but I kind
of have some experience in that specific setup. Are you sure freeswitch
supports storing *and* loading dialog informations from a DB? In sofia-sip
the dialog info is managed internally in the NTA agent, so that then when an
in-dialog request arrives it can match it to the proper dialog leg and
process it. This, assuming a stateful proxy. Now, you would need to make
sure that the new heartbeat-started freeswitch is actually loading that
dialog info from a DB and restoring the dialog legs internally. If this is
not done, sofia-sip won't be able to find a proper dialog leg match and will
return by default that SIP 481.
