We connect freeswitch using odbc connection for device registration on server.

Now the problem occur when Freeswitch crashed,down or restart uncertainly that time the entry does not removed from sip_registration table and next time user are not able to make the call.

Then we have to manually delete that entry from database to make it working.

OS : Debian8
FS version : FreeSWITCH Version 1.6.6~64bit ( 64bit)

can anybody help us to resolve this issue?
