I have a customer with an analog pbx system now that I am changing over to a sip system. They have a few lines that need to still have analog connectivity so I am installing a Cisco/Linksys SPA8000. One of my issues is with a 2-way PA system between their main office and shop. They have a Viking Model HF-3W paging system presently that allows them to communicate both ways without having to pick up a phone at the shop. I need to set the SPA8000 to have one port auto answer for this paging system but I am not sure how.
