Mitel CS-5200 version 3.2.4.8. We occasionally receive calls where the caller goes to voice mail, hangs up, but the system does not recognize that the caller has hung up, and goes on to record a 30 minute blank voice mail. We have worked with our phone service provider and they have changed settings on their end, as well we have tweaked settings on out end. They have helped but it is still an occasional problem. We would like to limit the length of voicemail messages to two minutes, rather than the default of 30 minutes, since most of these calls come in on 800 lines and we are being charged for calls that don't exist. Where do I change this setting? Sorry I'm sure this is a stupid question but I am an IT person and managing the phone system is not my forte - it just sort of fell in my lap! Any help would be greatly appreciated!
