I've just got my phone and fax lines into the office. They are both IP based, which isn't a big problem as they are providing the phone. My fax however is on a HP Photosmart 7280 and has an analog line in. Which of these adaptors do I need to convert the connector?
PABX Full MAster: PRO SIGNAL|31064R|RJ45 TO PABX FULL MASTER | CPC
PABX Master: PRO SIGNAL|31070R|RJ45 TO PABX MASTER | CPC
Or some other?
