laforge gerrit-no-reply at lists.osmocom.orglaforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/24232 ) Change subject: sccp: Add TC_callingparty_ssn_only() ...................................................................... sccp: Add TC_callingparty_ssn_only() This test verifies that libosmo-sccp will properly respond to SCCP traffic that only has a SSN in the CallingPartyAddress. That situation poses the unique challenge of how to route a response, as we lack a GT and a PC to do the routing. In order to support this, libosm-sccp now adds the PC into the CallingPartyAddr when passing such messages from M3UA to SCCP. This way the recipient can simply respond back to that address and it will be routed on PC.
