I have been messing with this SPA122 all day and still have not got this to work. I orginally tried to setup it up under Fax Extensions and could not get it to be able to dial out. I then made it a regular extension and have gotten it to dial out, but the other line is always busy and has to redial numberous times. The fax machine I have hooked up to it is a Lexmark MX511de. I have followed a couple of guides I found online. Is there some other features I need to configure on the devices? Guide 1 - http://www.k2systems.ca/helpdesk/knowledgebase.php?article=137 I have found a couple of other information posts about it. and have used some 3102 posts. Which it looks like most are removed. Any help is appreciated. Our current fax solution is not working out well. I am trying to get this setup so i can drop the other.
