Due to the migration to a multithreading scheme the timing behavior of
the stats items has slightly changed. There is now a 1 sec update cycle
in which the stats items are regenerated. This means we have to wait 1
sec. before we can query the endpoints.used stats item.

Since we now support wildcarded DLCX request, which so not necessarly
require a specific endpoint (the trunk is enough). We should also check
what happens when we send a DLCX request to a non existent endpoint. The
situation would be very similar. osmo-mgw will be unable to resolve the
endpoint, but the trunk will be resolved. However eventually the request
is not wildcarded and we expect that osmo-mgw is rejecting it.

The testcase TC_one_crcx_loopback_rtp_implicit triggers a bug in older

also means that all tests after TC_one_crcx_loopback_rtp_implicit will
also fail. Lets move TC_one_crcx_loopback_rtp_implicit to the end of the

The testcase TC_one_crcx_loopback_rtp_implicit uses
f_TC_one_crcx_loopback_rtp, which creates the RTP flow with IPv4
addresses but since we do not send a local RTP IP address with the CRCX
to the MGW, the MGW will prefer IPv6, which means that we get an IPv6
address back while the RTP strem is IPv4 on the TTCN3 side.

Send the remote address to MGW so it knows which IP version to return
during CRCX ACK. This actually better suits the test, since there's less
point in checking whether we receive something if we never pass the
IP/port to MGW. In any case, the "recvonly" should still tell MGW to
refrain from sending stuff to us, so we are really testing that here.

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.

osmo-mgw recently added support for E1 trunks via libosmoabis. While the
actual E1 plane may be difficult to test, there is some functionality
that can already be tested without having E1 support in TTCN3.
Lets add three testcases:
- TC_e1_crcx_and_dlcx_ep:
Does a CRCX to an E1 endpoint followed by a DLCX
- TC_e1_crcx_with_overlap:
Not all E1 endpoint combinations are possible at the same time. This
test verifies that invalid endpoint combinations are prevented.
- TC_e1_crcx_loopback:
Opes an E1 endpoint and tests if RTP loopback works (NO E1 traffic
involved)

The rtp payload test vector in TC_amr_oa_bwe_rtp_conversion is wrong, it
lacks the last byte which should be 0x00. Also the testvector is not
very well chossen since it after BWE conversion the actual payload does
not shrink (even if it looks like if it would because of the 0x00 byte
at the end). Lets pick a better payload from a real world trace that
actually shrinks by one byte when it is converted to BWE and use that

The testcase TC_ts101318_rfc5993_rtp_conversion tests the RTP packet
format conversion of ts101318 to rfc5993 and vice versa. At the moment

order to simplify the test and to make race conditions less likely, lets

The testcase TC_one_crcx_receive_only_rtp performs a short RTP
transmission that lasts about 1 second. Then it conuts out the number of
packets that are transmitted and checks against a fixed value. The
compare values are determined using experimentation and reflect the
number of bytes/packets that one could expect under normal conditions on
an average machine.
However, there may be load sitations on the test host that may cause that
a too little number of packets is transmitted and the test will fail. Lets
reduce the number a bit as the only thing we want to make sure with this
is that there are at least some (more than one or two) packets transmitted

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.

When stopping the test TC_two_crcx_and_unsolicited_rtp the unsolicited
RTP stream is not stopped. As a result it could happen that between
tearing down the other flows and stopping the test an unsolicited RTP
packet is sent to a closed socket.
The resulting ICMP destination unreachable packet translates to a
"Connection refused" error on the sending socket and fails the test.
Avoid this by making sure the unsolicited RTP sender is stopped before
stopping the test.

At the moment the RTP stream emulation is left in its default
configuration, this means that the payload type that appears in the RTP
stream is always 0. This may mismatch the payload type that is
configured with MGCP.
If nothing else is set, we should make sure that whan we create and modify
flows, the RTP emulation is always reconfigured to use the payload-type that
we set in the flow parameters. The other rtp-emulation parameters should
be set to their defaults.
- Make sure f_flow_modify and f_flow_create set the rtp flow parameters
