* The available number of channels on a media resource depends on the codec type of the active
calls. Calls utilizing the G.726 codec uses approximately 2% of the available resources, calls utilizing
the G.711 codec uses approximately 3%, and calls utilizing the G.729 codec uses approximately 8%.
E.g.: With 5 active G.729 calls and 10 active G.711 calls, the total resource utilization will be approx-
imately 70%.
