With my AVST CallXpress system there is one number you call to check your voicemail (3680) and a different on you can use to transfer a call directly into a mailbox (3681). In my case the process would be "transfer" 3681 <system prompts for mailbox number> "Relesae call"
My old Rolm PhoneMail system also had separate numbers to dial in to check messages or to transfer calls with, so your system may have something similar. Look at X2300 in your system to determine if it is a station, and if it is look at what the name is - does it say something like "Voicemail"? If so, do a DIS-PERSI:NAME; and look to see if there is an extension that says something like "Voicemail Transfer" or "Voicemail Direct" that you could use to transfer calls directly in.
