BYOC is an option offered by most major cloud-based unified communications and contact center providers that allows enterprises to connect to the PSTN via their own SIP trunking provider. This brings more control, lower rates, global coverage, increased quality, and better routing capabilities compared to bundled PSTN connectivity. However, IT managers need to weigh these benefits against potential drawbacks such as increased complexity, multiple service providers, and additional administrative overhead. The choice between BYOC and bundled PSTN connectivity depends on the organization's specific needs and priorities.
