Please pardon my previous post bluefox8080.
Yes, after looking at your point further I yield to the use of outboud rules as opposed to creating more development work (i.e. create a table for the admin to enter codes and have the rule created by the system in the background).
Ok, so all that's left is the view/print reports of calls made via individual rules, for billing purposes.
Any chance for 3CX Call Reporter providing report per rules usage?
