Hi Jayesh,

Maybe you should look into GRUU stuff ;).

On the TCP error - even if you set the TCP persistence flag, the UAC may 
close the TCP conn -> you end up in the same situation. What you can do 
is to prevent OpenSIPS to open TCP conns when routing to end-users - the 
idea is to have end-users connecting to OpenSIPS and not the other way 
around. See "tcp_no_new_conn_bflag" :
