The City is seeking a vendor to provide enterprise phone system replacement services, migrating from an on-premises Avaya system to a Cisco-based, cloud-first enterprise calling solution with hybrid survivability. The proposed solution must support approximately 263 users across at least eleven City facilities, with core voice gateways and survivability infrastructure at four primary City sites. The system must also address the needs of a mission-critical 24/7 Police Department non-emergency call center.

Key requirements include enabling flexible endpoint usage, simplified administration, robust security, and maintaining long-term architectural flexibility. Acceptable Cisco enterprise calling solutions involve Webex Calling or Cisco UCM Cloud/Dedicated Instance, with the architecture prioritizing cloud deployments combined with local survivability. Cisco must be the system of record for call control, PSTN, E911, voicemail, and survivability components.
