Check voicemail remotely without an IVR?

I have an Asterisk v1.2 server working with a voip provider (QuantumVoice) and a TDM4xx card with two pots lines. I do not use an IVR since I’m a one man show. The calls just ring a couple of extensions and then go to voicemail. Very basic. How do I check messages when I’m on the road? It appears I need an IVR so I can transfer myself to a special extension that is pointed to VoiceMailMain. Is there any way to just break the ringing or at least when the VoiceMailMain kicks in, can I press something and have it as for an extension etc.???

Try calling your number, when the voicemail kicks in, press the “*” button. It will ask for your password for that mailbox.
