We are attempting to network a Magix 4.0 to a IP Office 8.0.43. There were two Magix systems that were succesfully networked together and we upgraded one end to an IPOffice. We followed Avaya IP office tech tip #134 and havent had any success. The pt to pt circuit looks good, when we dial from the IPO to the Magix it actually takes the channel out of service. I was wondering if any one encountered similar problems. Thank you for your help.
