Cisco VOIP Engineer at a computer software company with 1,001-5,000 employees

Reliable customer communication and good third-party integrations with minor server update issues

Cisco supports third-party gadgets, including workforce management systems. These can be directly integrated with Cisco, a feature not widely supported by other contact centers. Additionally, redundancy is set up, meaning if one side of the server goes down, the other side will take over to prevent the contact center from completely failing.
