How to disable voicemail on an ext?

[Lanham10001]

We have few extensions that are setup in conference rooms but we do not want those to have their voicemail option turned on. How to disable the voicemail option?

thank you in advance for your assistance.

If 3300 then two options

1: They may be set up in call rerouting: usually as a call rerouting first alternative will be to voicemail. You just need to change that to (normally) 1 so it no longer works. You can check to see if 1 is the normal one by looking in call rerouting first alternative; looking for everything set to normal. No.1 is usually left alone for this purpose.

2: There could be individual call forwarding set on the sets. Use the superkey to go to call forwarding and see if anything is programmed /set. if so then just turn it off. (use the review key to check).
