Webex Calling

Webex local gateway

A local gateway is a customer-managed border that connects a Webex Calling location to premises PSTN.

  1. INVITE โ€” The location's PSTN choice sends the call to the gateway registered for it.
  2. INVITE โ€” The gateway's dial-peer selects the carrier or the PBX.
  3. 200 โ€” Answer and SDP.
  4. RTP โ€” Confirm the media addresses. Control Hub is not the RTP relay.

Calling Plan has no local gateway. If the design says Calling Plan, do not troubleshoot a CUBE that is not on the path. A location pointed at the wrong gateway fails only that location.
