When using

`KSR.tm.t_next_contacts`

The following error is shown:

``` PYT {INVITE}: 5(11047) INFO: <core> [core/kemi.c:86]: sr_kemi_core_info(): [18:27:34.526536] Loading destination routes PYT {INVITE}: 5(11047) ERROR: *** cfgtrace:request_route=[] c=[] l=0 a=26 n=append_branch PYT {INVITE}: 5(11047) ERROR: *** cfgtrace:request_route=[] c=[] l=0 a=26 n=append_branch PYT {INVITE}: 5(11047) INFO: <core> [core/kemi.c:86]: sr_kemi_core_info(): [18:27:34.692021] Test PYT {INVITE}: 5(11047) ERROR: tm [t_fwd.c:1723]: t_forward_nonack(): no branches for forwarding PYT {INVITE}: 5(11047) ERROR: sl [sl_funcs.c:362]: sl_reply_error(): stateless error reply used: I'm terribly sorry, server error occurred (1/SL) PYT {INVITE}: 5(11047) INFO: <core> [core/receive.c:277]: receive_msg(): request-route executed in: 167884 usec ```

Replacing the line that doesn't work with:

`msg.call_function("t_next_contacts")`

makes the script run as expected.

I'm running the master branch of Kamailio pulled yesterday.
