[cisco-voip] What's the pro and con for ATA, compared to FXS

Tue May 11 10:17:13 EDT 2010

One big change is that if you have CUWL mixed with UCL, you will need to have UCSS for each analog user.  I'm not sure how they will be assigned at this point.

I've been wondering about this.  Since v7, analog licenses can be purchased but there is no way to assign them.  Is this supposed to change in later versions of CUCM?
