We have an existing NEC 2000 with a third party voice mail system integrated In-Band (NOT MCI). MWI at the local NEC 2000 works fine. We just added a site with an NEC Elite IPK and it is CCIS networked with the NEC 2000 but I can't seem to light MWI across the CCIS network. I know this works with an MCI link because I've done it before. Any Ideas?
