Re: Support/Maintenance Agreements for AT&T VESTA 9-1-1 Call Handling System
To Whom It May Concern:
AT&T is the current equipment and maintenance provider of your current 9-1-1 VESTA solution for the city of Vernon (Police Department). Your AT&T VESTA equipment originally shipped 2018 is reaching 9 years of production. No other provider can maintain or access the AT&T supported system without compromising the security and integrity of the system. Maintenance take-over service for 9-1-1 call handling systems is not generally available. AT&T provides service to 404 of the 447 call handling solutions in the State of California. There is no existing provider of VESTA call handling that is trained/certified on the platform that can also support, including replacement hardware, your location with the 24x7x365 response time of AT&T. AT&T currently is a Single Vendor Solution to Vernon Police via this Sole Source justification and is the only provider for this proprietary solution. In addition, only AT&T certified technicians are allowed to maintain and do any modifications specific to your AT&T 9-1-1 system.
Please do not hesitate to call with any questions you may have. I can be reached at (951) 500-2130.
Sincerely,
