As a result, parameter multi_conn_mode is enabled for<br>SCCPlite and all code adapted to use that port in that type of scenario.<br>* iDuring calls when on SCCPlite, send a full (all-required-params-in)<br>CRCX through the MGCP-over-IPA connection towards the BSC in order to<br>emulate the MSC, and expect the correct answer back. This way we test<br>BSC funcionality to forward MGCP messages coming from MSC works as<br>expected.<br><br>Related: OS#2536<br>Depends: osmo-bsc.git
