[Freeswitch-users] Check Email remotely.

Hi All, How does a user check their FS voicemail when out of the office? We have an IVR on incoming calls. Dialing an extension goes to an extension and then its voicemail. We actually set it so that, for example, to go directly to voicemail for ext 20, you can dial 220. But then what? Is there a key to press while leaving voicemail to "auth" and check voicemail? We have pins set. Thanks, Sean
