NG CCTS Program

DIR is transforming the current Capitol Complex Telephone System (CCTS) to a Voice over IP (VoIP) platform.  We call it Next Generation CCCTS, or NG CCTS, and it changes how Texas agencies do business by reducing costs, improving efficiencies and increasing productivity.  This new platform will not alter agency telephone numbers or CCTS directory information, including any existing 800 numbers currently in use.

This new infrastructure is a state-of-the-art, feature-rich platform that will improve your agency's ability to access and use available technology.  This platform is delivering next generation technology to agencies so you can benefit from additional capabilities such as videoconferencing and instant messaging which bring remote workers closer and improves internal and external communications.

The new VoIP platform is dependent upon agencies' LAN network to provide telecommunications services to users.  All agencies will need to qualify their LAN networks as ready to support the new infrastructure.  As agencies qualify their LANs as ready for VoIP, they will become candidates for migration and scheduled accordingly. 

To make the upgrade as seamless as possible for agencies, DIR is using a phased migration approach to introduce NG CCTS to all agencies currently on today's version of CCTS.

Timeline of phased migration approach. Complete description is below.

As agencies prepare for the network migration, it's important to consider impacts to their organizations in terms of staff and project resources, any network ​remediation that may be required as well as specific migration costs that may be incurred during this process.

Getting Started with NG CCTS

Step 1: Establishing Agency Point of Contacts (PoC)

DIR will need each agency to provide a voice PoC to work with DIR to determine quantities, phone types, and ACD configuration (if applicable), as well as any other voice related items that arise throughout the migration.

DIR will also need each agency to provide a data networking PoC to work with DIR to help establish LAN readiness and determine WAN handoff configuration.

Step 2: Agency LAN Network Readiness

In order to be scheduled for the migration to NG CCTS, all agencies will need to determine their (LAN) network readiness for the new VoIP platform.  The network readiness evaluation walks agencies through the steps required to ensure the agencies network infrastructure is capable of providing the stability, reliability and performance needed to support the VoIP technologies of NG CCTS.

Step 3: Complete Agency Network Assessment Questionnaire

DIR requires completion of the (LAN) network assessment questionnaire and the telephony requirements questionnaire for all CCTS buildings for each agency.  This provides a more detailed view of an agency's network capabilities and helps establish a baseline for network performance with the new VoIP platform.  DIR will provide the questionnaires to you after contacting us at:

With the completion of this step, it is important to note that there may be remediation work required in order for an agency's LAN network to be deemed operationally ready.  This work must take place prior to scheduling an agency's migration.​

Step 4: Review the WAN Handoff Configuration Requirements

Each agency will need to work with DIR to establish a WAN handoff for their voice traffic.  This may be done using an existing connection to the WAN or it may require a new connection to the WAN, either way establishing how voice traffic will be handed off to the agency will need to be discussed and determined.  Please use the below WAN Handoff document as a means to understand the alternatives.

Step 5: Review the NG CCTS Product Catalog

Each agency will need to determine phone types and quantities.  To assist with the specific product selection available with NG CCTS, please review the product catalog.  DIR will also need to order your agencies phones prior to the migration, so it will be imperative to get quantities and phone types determined up front if possible.

NOTE:  Agencies should also contact DIR ( to get an initial meeting set up to cover an overview of the migration process, timing and to review the requirements (LAN, WAN, phones, costs, etc…).  DIR is here to help you with the migration as well as to assist agencies with any of the readiness requirements.  If you would like assistance or have additional questions, please contact DIR's NG CCTS team directly.​
