If you use VOIP DO NOT GO WITH BRINKS, I REPEAT DO NOT GO WITH BRINKS. They market their service as the only one in the industry to support VOIP. If you are having issues, they WILL NOT SERVICE YOUR ALARM UNDER THEIR CONTRACT. I had issues with Comcast and Brinks so I switched to U-verse and still had issues. Brinks says it is not their responsibility, its your ISP. They wont send anyone out unless you pay the 150$ per hour to test your system.
Here is where they get you: They note on your account at the time of installation that there are "service issues" with the ISP. Even though it works half the time. This is grounds for their argument when you call them and tell them its not working, "Oh, well we told you at the time of installation that we had issues with your ISP so its not our problem." Are you serious? So they sell a service, tell you it WILL work with VOIP but when it quits working they tell you to take a hike its not our problem. Unreal. DO NOT GIVE THIS COMPANY YOUR BUSINESS. Awful business practices and flat out awful company.
The research ive done is that they have had thousands of complaints but nothing has been done. Go with Brinks at your own risk.
