Improved business communications

Keep all your employees connected, whether your business is large or small. Our communication systems even have residential applications! Griffin Communications & Security Systems, Inc. has high-quality communications products available from Avaya (formerly AT&T) and ESI. With these systems, you'll have customization possibilities that allow employees to take business calls from home as if they were in the office.

Convenient communication with voiceover IP

The comprehensive communication systems available to you utilize voiceover IP, which will allow your phone communications to be tied together with the internet, making it easier for your employees to have access anywhere. We are not an internet providing company, but if you have a reliable internet connection, our voiceover IP devices will make communication so much easier! Feel free to contact us with questions or to discuss the products available.

Griffin Communications & Security Systems, Inc. achieves high call quality through innovative, patented technologies that allow us to monitor, analyze and react to the continual changes that occur not only in our own network elements but those of our supply partners as well. We analyze SIP signaling, node performance and IP metrics for all kinds of problems, ensuring that you receive the highest quality service.
