For call quality, Webex Contact Center supports at most a single upstream/northbound PSTN carrier forwarding calls into the connected PSTN service (Cloud Connected PSTN, Local Gateway, or Webex Contact Center PSTN); forwarding through a second intermediary carrier before reaching Webex Contact Center is explicitly unsupported due to added latency.
