ComTech manages and supports an enterprise-level communications platform that provides real-time communications to university stakeholders.

To maintain system reliability and compatibility, ComTech specifies and approves devices that connect to the university telephony system. Customers are encouraged to engage ComTech early in the communications projects to ensure compatibility and avoid additional integration costs.

Supported Devices

In recent years, ComTech has worked with NC State's ClassTech group and local vendors to standardize supported third-party SIP devices that are compatible with our telephony system.

Currently supported devices include:

• ClearOne VH20
• Biamp AudiaFlex-CM
• Biamp Tesira Forte

These devices have been tested and verified to work with our system.

Customers who choose supported third-party devices must pay:

• A one-time registration fee
• A one-time device license charge

Using Other Third-Party SIP Devices

Customers may choose to use other third-party SIP devices; however, additional requirements and charges apply.

If the device supports VoIP:

• The customer must provide a test device for lab evaluation. 
• A ComTech engineer will complete testing and configuration. 
• All licensing costs required for integration must be covered by the customer. 

ComTech supports only the device's telephony features. 

The device will be included in system patches and upgrades. The manufacturer is responsible for maintaining compatibility with current and future voice systems, including Cisco Call Manager. 

If a firmware update is required: 

• ComTech assists with applying the update. 
• If the device becomes incompatible due to firmware, the customer is responsible for replacement. 

Training and usage documentation will reflect the supported feature set and compatibility limitations.
