I am trying to get message notification on Kxtd 1232 with a TVS 100 voicemail. I have COS enabled and notification number set in the VM box. The system will not dial out. Could it be because the lines come in to a ISDN PRI card? I have all the settings correct I think. I have done this a few times before and never had any trouble. I think it has something to do with the ISDN PRI. Any ideas?

Thanks
