What is a key step in avoiding problems during VoIP installation?

A key step in avoiding problems during VoIP installation involves having customers verify that all devices work properly. This is crucial because ensuring that the devices intended for use with the VoIP system are functional can prevent a variety of issues that may arise post-installation. Problems such as compatibility issues, outdated firmware, or malfunctioning hardware can significantly disrupt the performance of the VoIP service. By verifying device functionality ahead of time, technicians can address any potential issues and facilitate a smoother installation and operational experience.

Other steps can contribute to a successful installation, such as confirming adequate internet speed and using reliable equipment; however, these do not replace the importance of ensuring that the customer's devices are in working order. Effective communication with the customer about their existing setup also adds to the overall reliability of the VoIP solution being provided.
