There were several problems along the way with call handlers created in the SA related to the default templates they're built off of - the primary call handler attached to the Default Subscriber template is the one used as the template - these were fixed along the way but this sounds somewhat familar.
Can you check the subscriber tamplte (the default one created by setup) and see if the standard greeting is enabled/disabled? If it's disabled and you can't enable it then you may consider rebuilding the default templates using the latest version of dbWalker.
If that's not the case there theres something else afoot.
