I have installed an ATA2 off of the MCK 6000 on the remote side and had some success in the past. I am on a project now and having a difficult time getting analog dial tone off of the ATA2. I replasced a couple ATA's and I did finally get dial tone. The fax machine will not send or receive, however. Is there any port configuration or such on the MCK for using an ATA that would help?
