From 55a954bba14f1625d3bb0ca80bdb501998c06309 Mon Sep 17 00:00:00 2001 From: Stefan Sperling Date: Wed, 3 Jan 2018 16:59:44 +0100 Subject: Support control connection status query for a particular MSC. Add a new control command 'msc.N.connection_status' which can be used to query the connection status of a particular MSC with number N. Keep the old control command 'msc_connection_status', which always queries MSC 0, for backwards compatibility.
