( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/15639 ) Change subject: MGCP_Test: Make RTP bwe/oa format conversation tests more robust ...................................................................... MGCP_Test: Make RTP bwe/oa format conversation tests more robust The following testcases are carried out using two bidirectional connections on one MGW endpoint. MGCP_Test.TC_amr_oa_bwe_rtp_conversion MGCP_Test.TC_amr_oa_oa_rtp_conversion MGCP_Test.TC_amr_bwe_bwe_rtp_conversion The test is programmed in a way that the TTCN3 side of the RTP emulation also works in bidirectional mode. This is prone to run into a race condition when the RX side is activated but the TX side is already transmitting. However, in order to test if the RTP format conversion works we do not need to test both directions at the same time. Its perfectly fine to do the one direction first and then do the other afterwards. Lets also add some guard time while switching the RTP flows.
