The Quest to find a Voip Switch

Commercial solution or open source l.jpg

  • Believe it or not, we actually considered a number of specialized

  • 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 Solution or Open Source ?

    • Open Source Pro’s specialized

    • 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.
