Commercial Solution or Open Source ? Believe it or not, we actually considered a number of Commercial solutions. After going through the pros and Cons of each solution we decided to go Open Source and decided on Freeswitch. When we considered the commercial alternatives we found the following CONS:  Higher initial Cost to implement.  Less Flexibility.  In some cases closed or partially closed architecture.  High support Cost.  Pay by the feature mentality.  Lack of ability to meet all of our needs which are constantly changing.

Commercial Solutions or Open Source ? Open Source Pro’s Obviously Cost, however deploying and Maintaining open Source is not Free. Ability to mold a system into anything you want it to be. In our case, we have integrated Freeswitch with our own custom LCR Logic which provides for quality based LCR and gives us the ability to do percentage based routing. We have also completely integrated Freeswitch and the Bat 1000 billing system to provide carrier billing, automated shutdown based upon prepaid balances, carrier reconciliation and rate management.
