Hi Spanton, thank you for writing back. This is the first VOIP application. The release is 25. I looked into upgrading to succession which is what I wanted because I come from a DMS/passport background (dont know much about meridian) but the boss doesnt want that because of the expense. Wont we have to upgrade to succession in order to use the pkg you are mentioning? Any idea of a ballpark figure on the pkg? We have all the patches required for QSIG. I thank you for your help.Cant a person just QSIG enable, run an ethernet to the dax and jumper off the dax to the cisco and install software on the pcs at the far end (as the cheapest solution).I have the interconnect info for the cisco and meridian.AJK
