So I am new to Elastix and have been setting it up for the past couple days. I got 2 extensions setup on my local network with softphones on 2 seperate computers. Once softphone is setup as the ext 3000 and the other one is setup as 3001. I can sit at the 3000 softphone and call the 3001 and it works fine, rings, I can answer and talk and everything. However, if I call from the 3001 machine and try calling the 3000 machine I get a busy tone. Any idea why this is? Thanks in advance.
