pespin gerrit-no-reply at lists.osmocom.orgpespin has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/20034 ) Change subject: mgw: Fix logic in test TC_two_crcx_mdcx_and_rtp ...................................................................... mgw: Fix logic in test TC_two_crcx_mdcx_and_rtp rtpem should be set to BIDIR at the same time where MDCX "sendrecv" is sent, otherwise if MGW sends us RTP packets (because we set the conn to sendrecv) they will be counted incorrectly in stats[0].num_pkts_rx_err_disabled. This issue doesn't trigger in current code because the MGW doesn't know anyway the remote IP address of the other connection until an MDCX is sent to it. However, if for whatever reason the IP address is known (for instance because it is set during CRCX, which will be done in next commits), then RTP messages would be sent and the error counter would be > 0.
