Did you work with the ISP and Phone company?
"As noted in a recent dialog at http://reviews.cnet.com/5208-7584-0.html?forumID=63&threadID=12420&start=0 this modem would not only need drivers, the ISP and phone company have to cooperate to supply such a feature."
"i am using modem on hold..i like it... you have to be using a V92 connection with your isp also must have call waiting with your phone company.... if you have a V92 modem then somewhere you probably have a modem on hold program on disk...maybe your restore disk...when the program is installed and working you will see a yellow telephone symbol at the bottom of your monitor near your clock....you gotta have all those things before it will work...."
As you can see, this stuff is not a plug it in and it works.
I run Win XP. I just bought a new modem that has modem on hold capability. It has no instructions on how to use it, however. I understand that you can make a 5 min. phone call while online, but it doesn't work. I installed everything from the CD just as they asked. And my call waiting is not disabled. Is there something I am not doing?
