I simply want to make a call from my extensions with whatever extra steps are necessary to use the unlimited INBOUND minutes of my trunk. Is this possible?
I am trying to utilize the callback and callthru features, but I am confused between the use of the two. I have an unlimited plan for incoming calls that I would like to use for calling out. Do I use callback or call through? Also, how do I use the feature with a softphone registered with the same pbx as extension? I know callback works when tested with my cell phone and callthru works when tested from other numbers. However, it does not quite meet the stated goal at least as far as I can tell.
Suggestions? Help? Explanation of the different uses of callback and callthru?
