[OpenSIPS-Users] dispatcher not doing fail over itself

[Bogdan-Andrei Iancu]

Hi,

Use debug=4 when doing the ds_next_dst() - see the setdebug() function :
http://www.opensips.org/Documentation/Script-CoreFunctions-1-11#toc47

Also try an avp_print() after ds_select_dst() to see what data is kept 
into transaction.
