laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/39951?usp=email ) Change subject: msc: add/expect network-originated MT-Forward-SM.Err ...................................................................... msc: add/expect network-originated MT-Forward-SM.Err The idea is to have two variants of the MT-Forward-SM.Err: * _MS: originated by the MS/UE (via RP-ERROR), * _NET: originated by the network (MSC) itself. In both testcase scenarios we expect the network to indicate the MT_FORWARD_SM_ERROR on its own, due to the lack of response from MS/UE. Use the right template kind for that, expect a specific Cause value.
