How is a VX system laid out?


This article shows a few general layouts for Telos VX systems. While these provide a good starting point, please consult with your dealer and/or Telos Alliance Support before ordering a VX system. We are happy to assist you in designing your system based on your requirements, usage, and interoperability needs.

Any information provided here regarding "Asterisk" or "FreePBX" servers refers only to Telos-commissioned FreePBX (Asterisk) servers used with Telos Alliance telephony products. While these are third-party servers and software, we are able to provide limited pointers and advice (like this article) under normal support. 

We are also happy to provide advanced, dedicated support and training on a VX and FreePBX system through various paid TelosCare Service Level Agreement options, or a la carte via our Dedicated Remote and Onsite Support service. Please use the Contact Us link above for more information on these options. We can guide you through this entire process.
