問題文
A bank has multiyear contracts with its incumbent on-premises PSTN carrier and will not break them, yet it wants inbound calls to arrive in the tenant. Which connectivity option fits, and why?
選択肢
- Cisco Calling Plan, because Cisco becomes the carrier of record and can resell the incumbent trunks under a single bill in over 140 markets.
- Webex Contact Center PSTN, because its tariff lets calls be delivered to agents at destinations such as a home worker in over 65 countries.
- Local Gateway, because the customer's own session border controller registers with Webex Calling and reaches over 140 markets while the incumbent carrier stays.
- Cloud Connected PSTN, because a certified provider in one of over 65 countries takes over the incumbent contract, keeps the numbers, and registers the customer's session border controller with Webex Calling on their behalf.
