Thanks for the clarification.
This is basically the scenario, where I've found a bug: - we are calling an unregistered user on our S-CSCF - we are sending an Server Assignment (SAR) to the HSS in order to retrieve the profile for the unregistered user - we trigger the Application Servers according to the users profile (ims_isc)
In the ims_isc module we have the following code:
``` if (is_route_type(FAILURE_ROUTE)) { /* need to find the handling for the failed trigger */ ```
I'll check the ims_isc module for a better fix.
