[SR-Users] failure_route send 500 retry later

[Alejandro Mellado G.]

Hi' Carsten,

Of course that t_on_failure is in request route.
I think that  in kamailio is the problem, because the forward  not 
arrive to SEMS and kamilio log says:

  2(96827) DEBUG: <core> [usr_avp.c:639]: DEBUG:destroy_avp_list:
