Nevertheless I have other proposals like Elastix miniUCS, Digium G400, Rhino PBX, Elastix setup on computer, etc.
Besides the PBX is going to manage E1 trunk. ... I would like to know your opinion about to buy dedicated pbx hardware like Openbox IX132 or buy a computer, buy a E1 card and setup asterisk / Elastix. Which are the pros and cons?
Please, avoid copy and paste curriculum as your answer, I would like to know more about your propose about this project.
