I enter MagicJack/1.80.466c (SJ Labs)
for the agent but I noticed that it defaults back to 0 everytime that I close the softphone down... How can I get it to save it?
You need to save the settings before exiting the menu. If that doesn't work, you need to address this with the folks who support Eyebeam, as this problem is unrelated to MJ operations.
