Which of the following methods can be used to connect a Customer Site to the PSTN for a partner?

Connecting a Customer Site to the Public Switched Telephone Network (PSTN) is essential for enabling voice communication between the customer and the broader phone network. The method of using a Local Gateway establishes a physical or logical connection that allows calls to be routed from the customer’s site directly to the PSTN.

A Local Gateway processes the voice signals and converts them to a format suitable for transmission over the PSTN. This ensures a seamless integration of on-premises resources with external telephony services. It can handle task elements such as call routing, signaling, and even local call processing. This is especially pertinent for businesses that require reliable and efficient voice communication while maintaining control over their local telephony environment.

While Cloud Connected PSTN provides cloud-based connectivity options and could be suitable in those contexts, the specific reference to connecting a customer site directly illustrates the use of a Local Gateway as a more traditional method for such connectivity.

The other choices, such as using a Local Gateway not connected to a PSTN, do not fulfill the requirement of establishing a connection to the PSTN, as they imply a local setup without external connectivity. Likewise, while a Cisco PSTN suggests connectivity, it lacks the specificity needed for a direct customer setting, as it does not clarify the
