[OpenSIPS-Users] Using dispatcher and t_replicate()

[Bogdan-Andrei Iancu]

Hi Jody,

in 1.6.4, it seams that $du is NULL (no value) - are you sure the 
ds_select_dst() was successful ? put it in an "if" statement :

    if ( ds_select_dst("1", "4") ) {
          xlog("replicating to $du \n");
          t_replicate("$du");
    } else {
          xlog("failure to select");
    }

Regards,
Bogdan
