+Subject: [PATCH 1/2] nta.c/leg_find: Fix 'by method' leg matching condition
+
+  In certain cases 'leg_method' might be null so the IF statement:
+
+    if (leg_method && method_name && !su_casematch(method_name, leg_method))
+      continue;
+
+  is not working at all despite 'method_name' is not null. It leads to
+  leg matching process returns false positive at:
+
+    if (loose_match == NULL)
+      loose_match = leg;
