Contact our sales department for more information on partnering with us.

Depending on your time frame, budget and technical expertise you can decide to:

  • Build your own telephony solution by buying our hardware and downloading our freely available open source software.
  • Engage us to remotely install all the necessary software on your very own PC server and get it up and operational.
  • Buy a Voicetronix pre-configured telephony server solution with all hardware, drivers and telephony application software installed, burnt in and ready for deployment, or
  • Ask us to develop a custom solution.
Whichever option you choose, we provide all our customers free email and phone support for our products. If you can still find bugs in our hardware or code, that's our problem and we want to hear about it.
