What is cacOverrun?
This OID reports a cumulative counter of times Call Admission Control rejected calls because limits were exceeded since startup. Engineers use this to justify policy increases or infrastructure expansion when threshold violations become frequent. A value of 1247 indicates over 1200 calls were denied due to capacity constraints.
Examples
