The MGW<br>is expected to deduct the destination address from the first incoming<br>RTP packet and loop it back to its originating address.<br><br>Change-Id: I7baf827fb0c3f33e13ccbaffd37ba0eb4e20c304<br>Related: OS#5123<br>---<br>M mgw/MGCP_Test.ttcn<br>1 file changed, 18 insertions(+), 2 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.osmocom.org:29418/osmo-ttcn3-hacks refs/changes/73/24173/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;"><span>diff --git a/mgw/MGCP_Test.ttcn b/mgw/MGCP_Test.ttcn</span><br><span>index f6dfe57..c4f97a8 100644</span><br><span>--- a/mgw/MGCP_Test.ttcn</span><br><span>+++ b/mgw/MGCP_Test.ttcn</span><br><span>@@ -1693,7 +1693,7 @@</span><br><span> </span><br><span> /* Create one connection in loopback mode, test if the RTP packets are</span><br><span> * actually reflected */</span><br><span style="color: hsl(0, 100%, 40%);">- testcase TC_one_crcx_loopback_rtp() runs on dummy_CT {</span><br><span style="color: hsl(120, 100%, 40%);">+ function f_TC_one_crcx_loopback_rtp(boolean one_phase := true) runs on dummy_CT {</span><br><span> var RtpFlowData flow;</span><br><span> var MgcpEndpoint ep := c_mgw_ep_rtpbridge & "1@" & c_mgw_domain;</span><br><span> var MgcpCallId call_id := '1225'H;</span><br><span>@@ -1702,7 +1702,7 @@</span><br><span> f_init(ep);</span><br><span> flow := valueof(t_RtpFlow(mp_local_ipv4, mp_remote_ipv4, 111, "GSM-HR-08/8000/1"));</span><br><span> flow.em.portnr := 10000;</span><br><span style="color: hsl(0, 100%, 40%);">- f_flow_create(RTPEM[0], ep, call_id, "loopback", flow);</span><br><span style="color: hsl(120, 100%, 40%);">+ f_flow_create(RTPEM[0], ep, call_id, "loopback", flow, one_phase := one_phase);</span><br><span> </span><br><span> f_rtpem_mode(RTPEM[0], RTPEM_MODE_BIDIR);</span><br><span> f_sleep(1.0);</span><br><span>@@ -1722,6 +1722,21 @@</span><br><span> setverdict(pass);</span><br><span> }</span><br><span> </span><br><span style="color: hsl(120, 100%, 40%);">+ /* Create one connection in loopback mode, test if the RTP packets are</span><br><span style="color: hsl(120, 100%, 40%);">+ * actually reflected */</span><br><span style="color: hsl(120, 100%, 40%);">+ testcase TC_one_crcx_loopback_rtp() runs on dummy_CT {</span><br><span style="color: hsl(120, 100%, 40%);">+ f_TC_one_crcx_loopback_rtp(one_phase := true)</span><br><span style="color: hsl(120, 100%, 40%);">+ }</span><br><span style="color: hsl(120, 100%, 40%);">+</span><br><span style="color: hsl(120, 100%, 40%);">+ /* Same as above, but we will intenionally not tell the MGW where to</span><br><span style="color: hsl(120, 100%, 40%);">+ * send the outgoing traffic.
