License count for VALUE_CM_AMS_VOIP_CHLS is innternally tracked on CM only, Current usage can be checked by "display capacity" CM SAT command. No license count / usage % is tracked on SMGR / WebLM.. This works as designed. If change of current behaviour is required, then a GRIP request needs to be submitted.
Note: FAQ107559 explains on AMS license types and also implies the above described behaviour.
