Asterisk can surely do it, but you need some provisioning.

Assume you have an internal number to call to reach your voicemailbox 
(VoiceMailMain). Let's say its 8000 in your local context. You could then 
probably use 'sip:8000 at asteriskbox.internal.net' in the Pingtel phone.

It can be made a little more userfriendly if you support matching 
callerid's with voicemailboxes. For example, on one of my local boxes I 
used a little AGI script, containing:

--------------
switch($clid) {
   // enter the mailbox number for each valid callerid
   // prepend 's' if you wish to trust the callerid and skip the password check
   case "3001":  $parms = "s3000"; break;
   case "0612345678":    $parms = "s3000"; break;
   default: $parms = "0"; break;
}
if($parms != "") $parms = " $parms";

echo "EXEC VoiceMailMain$parms\n";
--------------

This allows the user to skip the username and password prompts and go 
directly to their mailbox.

Hope this helps.
