[Serusers] Voice Mail options for an SER environment

Hello: I'm interested in how this community is providing voicemail service to IP phone users registered to a SER proxy. If you can speak to this point I'd appreciate any feedback you can provide. Specifically I'm interested in: 1) What product is providing voice mail service? 2) With this system can users manipulate messages via the telephone set? 3) If the answer to #2 is yes then how is this functionality implemented. Do you provision a lead number for users to call into voicemail?
