Here are a few things to check: The amount of memory (storage) for the basic voice mail provided on the processor card is surprisingly weak for a system of this size. Has a separate VMIB card been added to expand the overall capacity? Even if so, the system must be programmed to use this card exclusively for voice mail. If not, it will continue to use the basic capacities. Second: What kind of lines are being used? If they are POTS lines, be sure that you're receiving disconnect supervision from the CO. If not, voice mail messages will continue to record 'dead air' after the caller hangs up, eating up the available memory. This is a common issue, especially when customers switch to service providers that don't provide this. VoIP and CATV providers often don't provide positive disconnect without specifically asking for it when using POTS lines. Unfortunately, due to added use of pair-gain equipment even with real telcos, they often don't send it. No service provider will acknowledge this. You will have to prove it and assist the customer in fighting this battle.

If they are using PRI or SIP trunking, then disconnect supervision is likely not your issue and it may be simply a case of not enough memory or an improperly allocated VMIB card.
