# How is a VX system laid out?

## Scope

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.*

> [!NOTE]
> We are also happy to provide advanced, dedicated support and training on a VX and FreePBX system through various paid [TelosCare Service Level Agreement](http://telosalliance.com/teloscare) 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.
