VOIP is an interconnection protocol. In order to connect a VOIP device to the general telephone network, you need a gateway that is willing to do the conversion. The gateway will pay telephone tolls, so they are generally password-protected and charge you a fee. However, if WebEx has a public SIP interface, you can have any SIP VOIP program -- there are lots of them -- talk directly to that, without passing through a telephone gateway. A little googling shows me this page: https://help.webex.com/en-us/7yxpa9/Join-a-Webex-Meeting-from-a-Video-System and this one: https://help.webex.com/en-us/7ej8gq/Requirements-for-Business-to-Business-B2B-SIP-Calls-To-and-From-the-Cisco-Webex-Cloud which might be helpful. If you want to buy services from a telephone gateway service, they are generally quite cheap -- US 1 cent per minute is a reasonable price for outbound US calls in no particular volume. -dsr-
