is there a way of counting the number of calls a customer has without involving additional external scripting such as perl, lua, databases, etc?

I tried to use the dialog module with set_dlg_profile() function but I wasn't able to provide the profile name using a pvar, instead a string constant was needed and, in my case, the nature of the name was dynamic and couldn't be specified statically.

The original intention was to limit the amount of simultaneous calls using the proper methods but since it wasn't possible, at least the way I wanted to do it, I added this functionality to the cnxcc module which has all the necessary information to properly handle these scenarios.
